Question

When material subjected to load then elongation becomes more faster beyond the yield point.

(a) True

(b) False

I have been asked this question in exam.

This intriguing question originated from Relationship between Tensile and Shear Yield Stress in portion Types of Die & Metal Forming Processes of Casting-Forming-Welding II

Answer 1

Right choice is (a) True

Explanation: Beyond the yield point, as the load increases, elongation of material proceeds at a faster rate than before. This part of stress strain curve is called as hardening region. When the load reaches a maximum value, the engineering stress at this point is called as the tensile strength or ultimate tensile strength of the material.
