Question

Which of the following is true for sine table?

(a) Sine table is most convenient for the light workpieces

(b) Procedure of setting angle is not same as sine bars

(c) Table may be safely swung from 0 to 90 degrees

(d) Error caused by clamping mechanism is very large

I had been asked this question during a job interview.

This interesting question is from Sine Principle and Sine Bars in chapter Angular Measurement and Circular Division of Engineering Metrology

Answer 1

Correct choice is (c) Table may be safely swung from 0 to 90 degrees

Easiest explanation: Sine table is the development of the sine bar. It is the most accurate and convenient design for heavy workpieces. The principle of setting sine table at any angle is same as for sine bars.
