Sample Questions
When a wire is stretched, the restoring force per unit area is called:
Show answer
Stress
Stress is the internal restoring force per unit area of cross-section of a deformed body.
Which of the following materials is closest to being perfectly elastic?
Show answer
Quartz fiber
Quartz fiber is the nearest approach to a perfectly elastic body as it regains its original shape completely after deformation.
What happens to intermolecular forces when the separation between molecules is greater than the equilibrium separation?
Show answer
They become attractive
When molecular separation exceeds equilibrium distance (R₀), the net force becomes attractive.
Which of the following is NOT a type of stress?
Show answer
Gravitational stress
The three types of stress are longitudinal, normal, and shearing. Gravitational stress is not a defined term in elasticity.
