LATHE ACCESSORIES - Practice Mode

1) Where will be using the angle plate and counter weight?
Correct Answer: Face plate
Explanation:

The point through which the Whole mass of the body acts, irrespective of the position of the body, is known as centre of gravity (briefly written as c.g.). The plane geometrical figures (like rectangle, triangle, circle etc.) have only areas but no mass. The centre of area of such figures is known as centroid or centre of gravity of the area of the body. It may be noted that every body has one, and only one, centre of gravity.

Mass affects the centre of gravity of the object.

2) Which work holding device of lathe is require to balance for irregular job?
Correct Answer: Face plate
3) Which material is used for making lathe bed?
Correct Answer: Grey cast iron
Explanation:

The point through which the Whole mass of the body acts, irrespective of the position of the body, is known as centre of gravity (briefly written as c.g.). The plane geometrical figures (like rectangle, triangle, circle etc.) have only areas but no mass. The centre of area of such figures is known as centroid or centre of gravity of the area of the body. It may be noted that every body has one, and only one, centre of gravity.

Centre of gravity of a circle lies at its centre.

4) Which part of centre lathe make angular movement?
Correct Answer: Compound slide
Explanation:

The point through which the Whole mass of the body acts, irrespective of the position of the body, is known as centre of gravity (briefly written as c.g.). The plane geometrical figures (like rectangle, triangle, circle etc.) have only areas but no mass. The centre of area of such figures is known as centroid or centre of gravity of the area of the body. It may be noted that every body has one, and only one, centre of gravity.

Centre of gravity of a right circular cone from its base.

5) What is the purpose of square slot provided on the top of the pinion of a 3 jaw chuck is?
Correct Answer: To accommodate the chuck key
