### Hammer can be classified according to their?

• A.

Pane

• B.

Pin

• C.

Wedge

• D.

Handle

A. Pane
Explanation
Hammer can be classified according to their pane, which refers to the flat, striking surface of the hammer head. Different types of hammers have different pane shapes and designs, such as cross pane, straight pane, or ball pane. The pane plays a crucial role in determining the type of work a hammer is suitable for, as it affects the force and precision of the strike. Therefore, classifying hammers based on their pane helps in selecting the appropriate hammer for specific tasks.

A. Taper Reamer
Explanation
A taper reamer is used to make a hole taper. It is a cutting tool with a tapered shape that gradually widens towards the end. This allows it to gradually enlarge and shape a hole to a specific taper angle. Taper reamers are commonly used in metalworking and woodworking industries to create tapered holes for various applications, such as fitting tapered pins or creating a conical shape for joining parts together.

### Tap is a process of making?

• A.

• B.

• C.

Making Bore

• D.

Making a hole

Explanation
Tap is a process of creating internal threads in a hole or a pre-drilled bore.

### Least count of Vernier caliper?

• A.

0.022 mm

• B.

0.02 mm

• C.

0.002 mm

• D.

2.00 mm

B. 0.02 mm
Explanation
The least count of a Vernier caliper refers to the smallest measurement that can be accurately read from the instrument. In this case, the correct answer is 0.02 mm, which means that the Vernier caliper can measure increments as small as 0.02 mm.

### To measure the outside diameter of an object we can use

• A.

Out-side micrometer

• B.

Vernier Caliper

• C.

Out-side Caliper

• D.

All.

D. All.
Explanation
The correct answer is "All" because all three tools mentioned - outside micrometer, Vernier caliper, and outside caliper - can be used to measure the outside diameter of an object. Each tool has its own advantages and is suitable for different situations, but all of them are capable of providing accurate measurements of the outside diameter.

### What is recommended cutting angle of chisel for steel?

• A.

70 degree

• B.

60 degree

• C.

50 degree

• D.

40 degree

A. 70 degree
Explanation
A chisel is a cutting tool used for shaping and carving materials such as wood or metal. When working with steel, a chisel with a recommended cutting angle of 70 degrees is preferred. The higher cutting angle provides a sharper edge, allowing for more precise and efficient cutting through the tough steel material. A lower cutting angle may not be as effective in cutting through steel and may result in less clean and accurate cuts.

### For smoothing the surface which TPI of file is required?

• A.

50 TPI

• B.

40 TPI

• C.

30 TPI

• D.

20 TPI

A. 50 TPI
Explanation
To smooth the surface, a file with a higher TPI (Teeth Per Inch) is required. The higher the TPI, the finer the teeth on the file, which allows for a smoother finish. Therefore, the correct answer is 50 TPI.

### A vice is a device used for holding jobs?

• A.

True

• B.

False

A. True
Explanation
A vice is indeed a device used for holding jobs. It is a mechanical tool that consists of two parallel jaws, one fixed and the other movable, which are used to securely hold and clamp objects in place. The jaws can be tightened or released using a screw mechanism, allowing for a firm grip on the workpiece. Vices are commonly used in woodworking, metalworking, and other applications where stability and precision are required.

Rate this question:

• 12.

### Chisel can be classified according to its pane ?

• A.

True

• B.

False

B. False
Explanation
Chisel cannot be classified according to its pane because a chisel is a cutting tool that consists of a handle and a sharp metal blade, typically used for shaping or carving wood, stone, or metal. The classification of chisels is typically based on their size, shape, and purpose, rather than the type of pane they have.

### Mallet is a type of soft hammer?

• A.

True

• B.

False

A. True
Explanation
Mallet is indeed a type of soft hammer. Unlike regular hammers, mallets have a large, usually wooden head that is softer and less likely to damage the surface being struck. They are commonly used in woodworking and other delicate tasks where a softer impact is required. Therefore, the statement "Mallet is a type of soft hammer" is correct.

### Mushroom head chisel can be used until a new chisel is issued?

• A.

True

• B.

False

B. False
Explanation
The statement is false because a mushroom head chisel should not be used until a new chisel is issued. A mushroom head chisel is a chisel that has a damaged or deformed head, typically caused by excessive use or misuse. Using a mushroom head chisel can be dangerous as it may not provide the proper cutting or striking surface, leading to accidents or ineffective work. It is important to replace a mushroom head chisel with a new one to ensure safety and efficiency in chiseling tasks.

### Move the chisel across the face of the grinding wheel while sharpening a chisel with angle grinder?

• A.

True

• B.

False

A. True
Explanation
When sharpening a chisel with an angle grinder, it is important to move the chisel across the face of the grinding wheel. This helps to ensure an even and consistent sharpening of the chisel blade. If the chisel is held in one spot or moved in a random manner, it may result in an uneven sharpening, leading to an ineffective chisel. Therefore, it is necessary to move the chisel across the face of the grinding wheel while sharpening with an angle grinder.

• 16.

### The length of file can be consider from the point to the tip of face of file?

• A.

True

• B.

False

B. False
Explanation
The length of a file cannot be considered from the point to the tip of the face of the file. The length of a file is typically measured from the base of the handle to the tip of the file, excluding any additional parts or attachments. Therefore, the statement is false.

Rate this question:

• 17.

### Adjustable reamer can be used to enlarge the hole?

• A.

True

• B.

False

A. True
Explanation
An adjustable reamer is a tool that can be adjusted to different sizes, allowing it to be used to enlarge a hole. By adjusting the reamer to the desired size, it can be inserted into a smaller hole and then rotated to remove material and enlarge the hole to the desired size. Therefore, it is true that an adjustable reamer can be used to enlarge a hole.

### For drilling in brass we need 200 degree of cutting angle?

• A.

True

• B.

False

B. False
Explanation
The cutting angle required for drilling in brass is typically around 118 degrees. A cutting angle of 200 degrees would be excessive and not suitable for drilling in brass. Therefore, the statement is false.

### A rachet nut is used in a micro meter for accurate filling?

• A.

True

• B.

False

A. True
Explanation
A ratchet nut is indeed used in a micrometer for accurate measuring. The ratchet mechanism allows for precise adjustment and locking of the measurement, ensuring accurate readings. This feature is especially important in applications where precision is crucial, such as in engineering, manufacturing, and scientific research.

• 20.

### Angle protector is used to measure the angle between two edges ?

• A.

True

• B.

False

A. True
Explanation
Angle protector is a tool that is specifically designed to measure the angle between two edges. It is used in various fields such as carpentry, construction, and engineering to ensure accurate measurements and precise angles. By placing the angle protector on the edges, it provides a clear reading of the angle, allowing users to make necessary adjustments or calculations. Therefore, the statement that angle protector is used to measure the angle between two edges is true.
