State Hooke's law and graphically represent it.
OR
State Hooke's law Draw a labelled graph of tensile stress against tensile strain for a metal up to breaking point. Show the region Hooke's law is obeyed.

Hooke's law states

Hooke's law states that,

State the conditions under which Hooke’s law holds good.

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

A. What is static friction? B. State Hooke's law. C. Define Poisson's ratio.

The extension in a string, obeying Hooke’s law, is x. The speed of the wave in the stretched string is v. If the extension of string is increased to 1.5 x, then the speed of the wave in the string will be

A toy cart is tied to the end of an unstretched string of length 'l'. When revolved, the toy cart moves in horizontal circle with radius 2l and time period T. If it is speeded until it moves in horizontal circle of radius '3l' with period T_1 , relation between T and T_1 is (Hooke's law is obeyed)

Toy cart tied to the end of an unstretched string of length a, when revolved moves in a horizontal circle of radius 2a with a time period T. Now the toy cart is speeded up until it moves in a horizontal circle of radius 3a with a period T. If Hooke's law (F=kx) holds, then
