Question

For a 4-inch gage length, crosshead speed of a machine should not exceed ___________ inch up to yield point.

(a) 1/16

(b) 1/4

(c) 1/8

(d) 1/6

This question was addressed to me in an interview for job.

I'm obligated to ask this question of Aircraft Materials in chapter Testing Aircraft Materials of Aerospace Materials & Processes

Answer 1

Correct option is (b) 1/4

Easy explanation: The speed which a crosshead should not exceed until yield point is 1/16 for one inch per inch gage length per minute.

For 4 inches, it is – \(\frac{1×4}{16}\) = 1/4 inch.
