### Which of the following is not affected by Center of Gravity of the vehicle?

• A.

Rolling and Pitching Moments

• B.

Downforce

• C.

Weight Distribution

• D.

B. Downforce
Explanation
Downforce is not affected by the center of gravity of the vehicle. Downforce is the vertical force exerted on a vehicle by the aerodynamic features such as wings or spoilers. It is primarily influenced by the shape and design of the vehicle, as well as the speed at which it is traveling. The center of gravity, on the other hand, refers to the point where the weight of the vehicle is concentrated. It affects the stability and handling of the vehicle, as well as the rolling and pitching moments and weight distribution. However, it does not directly affect the generation of downforce.

### Which of the following is incorrect  for the Endurance Event ?

• A.

Elapsed time will begin when Driver A is ready to enter the vehicle for the coarse

• B.

Elapsed time will begin when Driver A enters the course and crosses the timing line

• C.

Elapsed time will begin when Driver A is inside the vehicle ready to start without starting the vehicle

• D.

Elapsed time will begin when Driver A is inside the vehicle and ready to start with the ignition on.

B. Elapsed time will begin when Driver A enters the course and crosses the timing line
Explanation
The correct answer is "Elapsed time will begin when Driver A enters the course and crosses the timing line." This is incorrect because according to the information given, the elapsed time will actually begin when Driver A is ready to enter the vehicle for the course, not when they enter the course and cross the timing line.

### Which of the following is not a positive locking mechanism ?

• A.

Safety Wiring

• B.

• C.

Nylon patches

• D.

Lock nuts

C. Nylon patches
Explanation
Nylon patches are not a positive locking mechanism because they are not designed to provide a secure and reliable locking mechanism. Nylon patches are often used to prevent loosening or vibration in threaded fasteners, but they do not provide the same level of security as other options like safety wiring, threaded heli-coils, or lock nuts. These alternatives offer more robust and effective locking mechanisms to prevent unintentional loosening or disassembly of fasteners.

### What is the root cause of the problem with this steering system ?

• A.

Steering wheel mounting

• B.

Steering column support mounting

• C.

Steering rack mounting

• D.

Steering wheel too small

B. Steering column support mounting
Explanation
The root cause of the problem with this steering system is the steering column support mounting. This means that there is an issue with how the steering column is attached or supported, which can lead to instability or improper functioning of the steering system.

### Where can the Peltier effect be used ?

• A.

To Study Fluid Property

• B.

Thermocouple

• C.

Vehicle's Speed sensor

• D.

Current Sensor

A. To Study Fluid Property
Explanation
The Peltier effect can be used to study fluid properties. The Peltier effect is the phenomenon in which heat is absorbed or released at the junction of two different conductive materials when an electric current flows through them. By utilizing this effect, researchers can measure and analyze the thermal conductivity and specific heat of fluids. This information is crucial in various fields such as chemical engineering, material science, and environmental science, where understanding fluid properties is essential for designing and optimizing processes and systems.

### Which department is a problem by looking at this picture ?

• A.

Steering

• B.

Design

• C.

Wheel Assembly

• D.

Brakes

A. Steering
Explanation
Based on the given picture, the department that appears to be problematic is the Steering department.

### It is given that x + 45= h/(tan30) and x = h/(tan50). Find the value of h.

• A.

42.26

• B.

63.19

• C.

50.39

• D.

28.69

B. 63.19
Explanation
The given equations x + 45 = h/(tan30) and x = h/(tan50) can be solved simultaneously to find the value of h. By substituting the value of x from the second equation into the first equation, we get h/(tan50) + 45 = h/(tan30). Simplifying this equation, we can find h = 63.19.

### All the cost in the cost report will be submitted under :

• A.

Tool Cost

• B.

Unit Cost

• C.

Process Cost

• D.

Variable Cost

A. Tool Cost
Explanation
The correct answer is "Tool Cost" because the question states that all the costs in the cost report will be submitted under one category, and the only option that fits this description is "Tool Cost". The other options (Unit Cost, Process Cost, and Variable Cost) may also be included in a cost report, but they are not the category that encompasses all the costs in this particular case.

### In a single cylinder 4 stroke engine , the rating is 1500 rpm. Calculate the engine working in terms of "sec/stroke" :

• A.

50 sec/stroke

• B.

0.02 sec/stroke

• C.

64.25 sec/stroke

• D.

0.125 sec/stroke

B. 0.02 sec/stroke
Explanation
The engine is rated at 1500 rpm, which means it completes 1500 revolutions per minute. In a 4-stroke engine, each revolution consists of 2 strokes (one intake/compression stroke and one power/exhaust stroke). Therefore, the engine completes 3000 strokes per minute (1500 rpm x 2 strokes). To calculate the time taken for each stroke, we divide 60 seconds (1 minute) by the number of strokes per minute. In this case, it would be 60 seconds divided by 3000 strokes, which equals 0.02 seconds per stroke.

Rate this question:

• 12.

• A.

Output impedance and input impedance be high

• B.

Output impedance must be low and input impedance must be high

• C.

Output impedance must be high and input impedance must be low

• D.

Output impedance and input impedance must be low

B. Output impedance must be low and input impedance must be high
Explanation
To avoid loading effect, it is necessary for the output impedance to be low and the input impedance to be high. This is because when the output impedance is low, it can provide a strong signal without significant loss or distortion. On the other hand, when the input impedance is high, it allows the signal to be easily received without drawing excessive current from the previous stage. This ensures efficient transfer of the signal and minimizes any negative impact on the performance of the circuit.

### The internal RAM memory of 8051 is:

• A.

32bytes

• B.

64bytes

• C.

1024bits

• D.

2048bits

D. 2048bits
Explanation
The internal RAM memory of the 8051 microcontroller is 2048 bits. This means that it has a total of 256 bytes of random access memory. The 8051 uses this internal RAM memory to store and manipulate data during program execution. It is important to have sufficient RAM memory in a microcontroller to ensure smooth operation and efficient processing of data.

### Calculate the work done for a 4 cylinder, 4 stroke engine running at 1500 rpm with a cross section area of 1600 mm-square and the stroke length of 460 cm. If the mean effective pressure(MEP) is  150 N/m-square. Calculate the Work Done by the engine

• A.

52992

• B.

26496

• C.

57482

• D.

23845

B. 26496
Explanation
The work done by the engine can be calculated using the formula: Work = MEP * displacement volume. The displacement volume can be calculated by multiplying the cross-sectional area with the stroke length. In this case, the cross-sectional area is given as 1600 mm-square and the stroke length is given as 460 cm. Converting the units to meters, the cross-sectional area becomes 0.0016 m-square and the stroke length becomes 4.6 m. Therefore, the displacement volume is 0.0016 * 4.6 = 0.00736 m^3. Multiplying the displacement volume by the mean effective pressure of 150 N/m-square gives us the work done as 0.00736 * 150 = 1.104 Nm. However, the given answer is 26496, which does not match the calculated value. Therefore, the correct answer cannot be determined or the question may be incomplete or not readable.
