Question

The extension under load method is easier to use in finding yield strength because ___________

(a) no necessity to plot a curve

(b) it is not easier

(c) it is the only method available

(d) randomness

The question was posed to me by my school principal while I was bunking the class.

Question is from Aircraft Materials in portion Testing Aircraft Materials of Aerospace Materials & Processes

Answer 1

The correct answer is (a) no necessity to plot a curve

Explanation: The extension under load method is used much more than the set method. This is due to the fact that the former method does not require the plotting of a curve to find the yield strength of a material.
