Question

An object is subjected to some force. As a result of the force object undergoes in the deformation. If deformation of length is 0.28mm and Actual length is 20 mm then, find simple strain.

(a) 0.014

(b) 10.0014

(c) 23.002

(d) 0.00215

The question was asked in my homework.

The question is from Structures Fundamentals topic in chapter Structures and Loads of Aircraft Design

Answer 1

Correct choice is (a) 0.014

For explanation I would say: Strain = change in dimension / original dimension = 0.28/20 = 0.014.
