A steel ring of radius r and cross section area A is fitted on to a wooden disc of radius R(Rgtr) . If Young's modulus be R, then the force with which the steel ring is expanded is

A metallic rod of radius 2cm and cross sectional area 4cm^(2) is fitted into a wooden circular disc of radisu 4cm . If the Young's modulus of the materail of the ring is 2xx10^(11) N//m^(2) , the force with which the metal ring expands is:

A steel ring is to be fitted on a wooden disc of radius R and thickness d. The inner radius of the ring is r which is slightly smaller than R. The outer radius of the ring is r + b and its thickness is d (same as the disc). There is no change in value of b and d after the ring is fitted over the disc, only the inner radius becomes R. If the Young’s modulus of steel is Y, calculate the longitudinal stress developed in it. Also calculate the tension force developed in the ring. [Take b lt lt r ]
