Under elastic limit the stess is

A

indirectly proportional to strain

B

directly proportional to strain

C

independent to strain

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
b
Hooke's law is applicable.
By Hooke's law, for small deformations.
`("Tensile stress")/("Tensile strain") = Y`
Is a constant for the given material. This ratio is called Young's modulus.
So. Within elastic limit, the stress developed is directly proportional to the strain produced in a body.
i.e., stress `prop` strain
or stress `= E xx` strain

Within the elastic limit, the ratio of shear stress and shearing strain is called

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
