MCQ
What is the definition of strain ?
Options
A) force per unit area
B) force per unit deformation
C) deformation per unit length
D) force per unit length
Correct answer : option C ( solution discussed below)
Solution
- The strain is a ratio of change in deformation per unit original length
= change in deformation
Length
- When load is applied on body that time body get deformed and this deformation per unit length is called as strain
So the Strain is a ratio of deformation per unit length
