According to Hooke's law of elasticity, if stress is increased, the ratio of stress to strain will be…………

Options

A. increases
B. decreses
C. becomes zero
D. remains constnat

Answer

D

Explanation

From Hokke.s law, from small deformation stress and strain are proportional to each other
`therefore` stress `prop` strain
`therefore` stress `= Y xx` strain
`therefore ("stress")/("strain") = Y,` which remain constant,
