13. What is the probability of getting a sum 9 from two throws of a dice?

Explanation

The probability of getting a sum of 9 from two throws of a dice can be calculated by finding the number of favorable outcomes and dividing it by the total number of possible outcomes. In this case, there is only one favorable outcome, which is getting a 3 on the first throw and a 6 on the second throw. The total number of possible outcomes is 6*6=36, as there are 6 possible outcomes for each throw. Therefore, the probability is 1/36, which simplifies to 1/9.

Submit
14. Anemometer is used to measure

Explanation

Anemometer is a device used to measure the velocity of wind or air. It works by capturing the force of the wind and converting it into a measurement of speed. By measuring the velocity, anemometers help in determining the speed and direction of the wind, which is crucial in various fields such as meteorology, aviation, and environmental monitoring. Therefore, anemometer is specifically used to measure velocity rather than pressure, viscosity, or density.

Submit
15. The measurement of a thermodynamics property known as temperature is based on

Explanation

The measurement of temperature is based on the zeroth law of thermodynamics, which states that if two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with each other. This law allows for the establishment of a temperature scale and the comparison of temperatures between different systems. By using the principles of the zeroth law, thermometers can be calibrated and measurements of temperature can be made.

Submit
16. If a bar of length, l, cross-sectional area, A, weighing, W, is fixed vertically at its upper end, its elongation is equal to

Explanation

When a bar is fixed vertically at its upper end, its elongation is determined by the weight applied to it and the material's properties. The equation Wl/2AE represents the elongation of the bar, where W is the weight, l is the length, A is the cross-sectional area, and E is the modulus of elasticity of the material. This equation is derived from Hooke's Law, which states that the elongation of an object is directly proportional to the applied force and inversely proportional to the cross-sectional area and modulus of elasticity. Therefore, the correct answer is Wl/2AE.

Similarly, the word pair "gauche:graceful" also represents an opposite relationship, where "gauche" means awkward or clumsy and "graceful" means elegant or poised. Therefore, the correct answer is "gauche:graceful".

Submit
18. The steel containing 0.8% carbon has a structure of

Explanation

The steel containing 0.8% carbon has a structure of ferrite because ferrite is the phase that forms in low carbon steels. Ferrite is a solid solution of carbon in iron, and it has a body-centered cubic (BCC) crystal structure. It is relatively soft and ductile, making it suitable for applications where toughness is required. In steels with higher carbon content, other phases such as pearlite, cementite, or martensite may form, but with 0.8% carbon, the dominant phase is ferrite.

Submit
19. Flywheel is used in

Explanation

A flywheel is used in a punch press to store and release energy. When the punch press is in operation, the flywheel spins and stores energy. This stored energy is then released to provide the necessary force for the punching action. The flywheel helps to maintain a consistent and smooth operation by storing and releasing energy in a controlled manner. This is particularly important in punch presses, where precise and powerful punches are required.

23. A ductile structure is defined as one for which the plastic deformation before fracture

Explanation

A ductile structure is one that can undergo significant plastic deformation before fracturing. This means that the material can be stretched or bent without breaking. The given answer, "is much larger than the elastic deformation," is correct because it indicates that the plastic deformation is greater than the elastic deformation. This implies that the material can withstand a large amount of deformation before it ultimately fractures, making it ductile.

Submit
24. The process of making cup-shaped parts from sheet metal blank pulling into dies with the help of punch is called:

Explanation

Drawing is the correct answer because it refers to the process of making cup-shaped parts from sheet metal by pulling the blank into dies with the help of a punch. This process involves stretching the metal to conform to the shape of the die, resulting in a cup-like form. Spinning involves rotating a flat sheet of metal while pressing it against a form to create a cylindrical shape. Extrusion involves forcing the metal through a die to create a continuous profile. Forming is a general term that encompasses various metal shaping processes.

Submit
25. Aptitude: From a group of 7 men and 6 women, five persons are to be selected to form a committee so that at least 3 men are there on the committee. In how many ways can it be done?

Explanation

From the given group of 7 men and 6 women, we need to select 5 people for the committee with at least 3 men.

We can consider two cases:
1) Selecting 3 men and 2 women:
The number of ways to select 3 men from 7 is 7C3 = 35.
The number of ways to select 2 women from 6 is 6C2 = 15.
So, the total number of ways to select 3 men and 2 women is 35 * 15 = 525.

2) Selecting 4 men and 1 woman:
The number of ways to select 4 men from 7 is 7C4 = 35.
The number of ways to select 1 woman from 6 is 6C1 = 6.
So, the total number of ways to select 4 men and 1 woman is 35 * 6 = 210.

Adding the two cases, we get a total of 525 + 210 = 735 ways.

Therefore, the correct answer is 735.

Submit

27. For a turning operation, the 'l' is the length of the job, 'f' is the feed rate and 'n' is the rpm of work. The cutting time for turning is calculated by:

Explanation

The cutting time for turning is calculated by dividing the length of the job (l) by the product of the feed rate (f) and the rpm of work (n). This is because the cutting time is inversely proportional to the product of the feed rate and the rpm of work. Therefore, the correct formula to calculate the cutting time is l / (f x n) minutes.

Submit
28. Following is (are) the function(s) of Flywheel.

Explanation

A flywheel has multiple functions. It stores and releases energy as needed during the work cycle, helping to maintain a consistent power output. It also reduces the amplitude of speed fluctuations, ensuring a smoother operation. Additionally, a flywheel can help in reducing the power capacity of the motor by providing an extra source of energy during peak demand periods. Therefore, all of the given options correctly describe the functions of a flywheel.

Submit
29. Heat transfer takes place according to

Explanation

The second law of thermodynamics states that heat transfer occurs from an object at a higher temperature to an object at a lower temperature. This law explains the direction of heat flow and the concept of entropy, which is the measure of the disorder or randomness in a system. It also states that it is impossible to convert all heat into work without any loss. Therefore, the second law of thermodynamics is the correct answer as it specifically deals with heat transfer.

Submit
30. In a cantilever, the bending moment is maximum at the

Explanation

In a cantilever, the bending moment is maximum at the fixed end. This is because the fixed end of the cantilever is the point where the cantilever is anchored or supported, and therefore experiences the highest amount of force or load. As a result, the fixed end undergoes the most significant bending moment compared to the other parts of the cantilever.

Submit
31. Heat is mainly transferred by conduction, convection and radiation in

Explanation

Heat is mainly transferred by conduction, convection, and radiation in boiler furnaces. In a boiler furnace, conduction occurs when heat is transferred through direct contact between the hot surfaces of the furnace and the surrounding materials. Convection takes place as the hot air or gases rise and circulate within the furnace, transferring heat to the surrounding areas. Radiation occurs as heat is emitted in the form of electromagnetic waves from the hot surfaces of the furnace, which can then be absorbed by nearby objects and surfaces.

Submit
32. Which of the following operation is required for making a chamfer on the edge of a hole?

Explanation

Counter sinking is the correct answer for making a chamfer on the edge of a hole. Counter sinking involves enlarging the top portion of the hole to create a flat or angled surface, which helps in reducing sharp edges and providing a chamfered effect. This operation is commonly used in metalworking and woodworking to improve the appearance and functionality of holes, especially when fasteners need to be flush-mounted or when the edges of the hole need to be chamfered for safety reasons.

Submit
33. The gears used to connect non-parallel and non-intersecting shafts is

Explanation

Spiral gears are used to connect non-parallel and non-intersecting shafts. Unlike straight bevel gears, which have straight teeth, spiral gears have angled teeth that gradually engage, resulting in a smoother and quieter operation. This makes spiral gears ideal for applications where precise and efficient power transmission is required, such as in automotive transmissions and industrial machinery. Double helical gears, on the other hand, are used to connect parallel shafts and are not suitable for connecting non-parallel and non-intersecting shafts.

Submit
34. Which one of the following is a lower pair?

Explanation

A lower pair refers to a type of mechanical joint where the relative motion between the two elements is a sliding or a rolling motion. In this case, a shaft rotating in a bush fits the definition of a lower pair as it involves a rotational motion of the shaft inside the bush, which can be considered as a sliding or rolling motion. On the other hand, a cam and follower mechanism involves a sliding or rolling motion as well, but it is classified as a higher pair due to the nature of the contact between the cam and the follower. Toothed gearing is also classified as a higher pair as it involves a rolling motion between the teeth of the gears. Therefore, the correct answer is shaft rotating in bush.

Submit
35. Kelvin temperature scale is based on

Explanation

The Kelvin temperature scale is based on the triple point of water. The triple point of water is the temperature and pressure at which all three phases of water (solid, liquid, and gas) can coexist in equilibrium. It is a well-defined and reproducible point, making it an ideal reference for temperature measurement. The Kelvin scale defines the temperature unit "kelvin" based on the triple point of water, with 0 K being absolute zero, the lowest possible temperature. Therefore, the triple point of water is fundamental to the establishment of the Kelvin temperature scale.

Submit
36. A process in which the working substance neither receives nor gives heat to its surroundings during expansion or compression is called

Explanation

An isothermal process is a process in which the working substance neither receives nor gives heat to its surroundings during expansion or compression. This means that the temperature of the substance remains constant throughout the process. In an isothermal process, the energy transfer occurs only in the form of work done on or by the substance, while the heat transfer is zero. This is in contrast to an adiabatic process, where there is no heat transfer but the temperature of the substance can change. A hyperbolic process is not a recognized term in thermodynamics, so it is not the correct answer.

Submit
37. Stainless steel is very difficult to grind due to its

Explanation

Stainless steel is very difficult to grind due to its toughness and ability to work harden. The toughness of stainless steel makes it resistant to deformation and breakage, making it challenging to grind. Additionally, stainless steel has the ability to work harden, meaning that it becomes harder and more resistant to grinding as it is subjected to mechanical stress. Therefore, both the toughness and work hardening properties of stainless steel contribute to its difficulty in grinding.

Submit
38. Verbal ability: the sentence below consist of a word or a phrase which is bold. It is followed by four words or phrases. Select the word or phrase which is closed to the OPPOSITE in meaning of the bold word or phrase.

Explanation

The word "retaliatory" means to respond to an action with a similar action, usually in a negative or aggressive manner. The word "perfunctory" means to do something in a routine or superficial manner, without much effort or interest. The word "conciliatory" means to make peace or to try to resolve a conflict by being cooperative and compromising. The word "circuitous" means to take a longer route or to go around in a roundabout way. Therefore, "conciliatory" is the word that is closest in meaning to the opposite of "retaliatory".

Submit
39. Verbal ability: Read the sentence given below to find out whether there is any grammatical error in it. The error, if any will be in one part of the sentence. The letter of that part is the answer. If there is no error, the answer is 'E'. (Ignore the errors of punctuation, if any).

Explanation

The sentence is in the past tense, so the correct form of the verb "clear" should be "cleared." Therefore, the error is in part C, "Cleared by clouds."

Submit
40. The process of joining two pieces in which a non-ferrous alloy is introduced in a liquid state between the piece of metals and allowed to solidify is known as

Explanation

Brazing is the process of joining two pieces of metal by introducing a non-ferrous alloy in a liquid state between them, which then solidifies. Unlike welding, which involves melting the base metals, brazing uses a lower temperature to melt the filler metal. This allows for the joining of dissimilar metals or metals with different melting points. The solidified filler metal forms a strong bond between the two pieces, creating a durable and reliable joint.

Submit
41. For a Newtonian fluid 

Explanation

In a Newtonian fluid, shear stress is proportional to the rate of shear strain. This means that as the rate of shear strain increases (i.e., the fluid is being deformed more rapidly), the shear stress also increases proportionally. This relationship is a characteristic of Newtonian fluids, which have a constant viscosity and exhibit linear behavior under shear. The proportionality between shear stress and the rate of shear strain is described by the fluid's viscosity, which determines how easily the fluid flows and deforms under applied forces.

Submit
42. Surface tension is due to

Explanation

Cohesion refers to the attraction between molecules of the same substance. In the case of surface tension, cohesion is responsible for the molecules at the surface of a liquid to be more strongly attracted to each other compared to the molecules within the liquid. This creates a "skin" or "film" on the surface, causing the liquid to behave as if it has a stretched surface. Therefore, cohesion is the main factor contributing to surface tension.

Submit
43. The heat is absorbed by

Explanation

The evaporator is the correct answer because it is the component in a refrigeration or air conditioning system that absorbs heat from the surrounding environment. It is responsible for evaporating the refrigerant, which in turn absorbs heat and cools the air or substance being refrigerated. The evaporator is typically located on the inside of the system and is where the cooling process begins.

Submit
44. A rack is a gear of infinite

Explanation

The correct answer is "Diameter." In the context of gears, the diameter refers to the size of the gear, specifically the distance across the gear from one side to the other, passing through the center. The diameter is an important parameter in gear design as it determines the overall size and compatibility of the gear with other gears in a system. The pitch, module, and number of teeth are also important parameters, but they do not define the gear as being "of infinite" like the diameter does.

Submit
45. Newton law of viscosity depends upon the

Explanation

Newton's law of viscosity states that the rate of shear strain in a fluid is directly proportional to the shear stress applied to it. In other words, the viscosity of a fluid determines how it responds to an applied shear stress. Therefore, the correct answer is "viscosity and shear stress" because these two factors are the key components in Newton's law of viscosity.

Submit
46. Which of the following does not give velocity ratio of gears?

Explanation

The correct answer is N1 / N2. This is because the velocity ratio of gears is determined by the ratio of the number of teeth on the gears, not the ratio of their speeds or diameters or torques. The formula for velocity ratio is N1 / N2, where N1 is the number of teeth on the first gear and N2 is the number of teeth on the second gear.

Submit
47. The drag force exerted by a fluid on a body immersed in the fluid is due to

Explanation

The drag force exerted by a fluid on a body immersed in the fluid is due to viscous and gravity forces. Viscous forces arise because of the fluid's resistance to flow and the friction between the fluid and the body. Gravity forces come into play as the weight of the body causes it to move through the fluid, creating a drag force.

Submit
48. Aptitude: The price of 10 chairs is equal to that of 4 tables. The price of 15 chairs and 2 tables together is Rs. 4000. The total price of 12 chairs and 3 tables is:

Explanation

Let's assume the price of 1 chair is x and the price of 1 table is y. According to the given information, 10 chairs = 4 tables, so 10x = 4y. Also, 15 chairs + 2 tables = Rs. 4000, so 15x + 2y = 4000. Solving these two equations, we can find the values of x and y. Once we have the values of x and y, we can calculate the total price of 12 chairs and 3 tables by multiplying the respective prices and adding them up. The total price comes out to be Rs. 3500.

Submit
49. The relative density of mercury is

Explanation

The relative density of a substance is defined as the ratio of its density to the density of a reference substance. In this case, the reference substance is usually water. Since the relative density of mercury is given as 1, it means that the density of mercury is equal to the density of water. Therefore, the correct answer is 1.

Submit
50. If the Reynolds number is less than 2000, the flow in a pipe is

Explanation

If the Reynolds number is less than 2000, the flow in a pipe is laminar. The Reynolds number is a dimensionless quantity that represents the ratio of inertial forces to viscous forces in a fluid flow. It is used to determine the type of flow, with values below 2000 indicating laminar flow and values above 4000 indicating turbulent flow. In this case, since the Reynolds number is less than 2000, the flow in the pipe is laminar.
