A 5 cm cube of a substance has its upper surface displaced by 0.5 cm, by a tangential force of 0.25 N. What is the modulus of rigidity of the substance ?

Text Solution

Verified by Experts

`theta = x/L = 0.5 xx 10^(-2)// 5 xx 10^2 = 0.1`
`eta = F//A tetha = 0.25/25 xx 10^(-4) xx 10^(-1) = 1000 N//m^2`
