Calculate the modulus of rigidity of a m...

Calculate the modulus of rigidity of a metal, if a metal cube of side 40cm is subjected to a shearing force of 2000N. The upper surface is displaced through 0.5cm with respect to the bottom. Calculate the modulus of rigidity of the metal.

Text Solution

Verified by Experts

`eta = (F)/(A theta)`
` theta = l/L = (0.005)/(0.40) = 0.0125`
` eta = (2.0 xx 10^3 N)/((0.16m^2). (0.0125))`
` = 1.0 xx 10^6 N//m^2`
