According to Hooke's law of elasticity, if stress is increaed, the ratio of stress to strain

A

becomes zero

B

remains constant

C

decreases

D

increases

Text Solution

Verified by Experts

The correct Answer is:
b
Hooke in 1679, showed experimentally that if strain is small, then the stress is propontional to strain. The ratio of stress to strain is constant for material of the given body and is called modulus of elasticity E. Thus,
`E = ("stres")/("strain")` = constant
Hence, it stress is increased, then the ratio of stress to strain remians constants.

According to Hooke's law, within the elastic limit stress/strain = constant. This constant depends on the type of strain or the type of force acting. Tensile stress might result in compressional or elongative strain, however, a tangential stress can only cause a shearing strain. After crossing the elastic limit, the material undergoes elongation and beyond a stage beaks. All modulus of elasticity are basically constants for the materials under stress. If stress/strain is x in elastic region and y in the region of yield, then
