What is Young’s modulus ?
Strain / Stress
Change in length / original length
Longitudinal stress / longitudinal strain
Stress / change in length

What is the property of a body by virtue of which it tends to regain its original size and shape by the removal of applied force is called?
Elasticity
Strain
Plasticity
Deformation

Remains constant
increases
None of these
decreases
5)
What does the following statement mean? “The elastic limit of steel is greater than that of rubber”.
Steel is more elastic than rubber
Rubber is more elastic than steel

What happen when bodies are deformed beyond elastic limit?
They suddenly turned back to its original shape
The modulus of elasticity decreases
All of the above
They stay permanently deformed
