Questions Part -1|Questions Part -2|Summary

A wooden wheel of radius R is made of two semicircular part . The two parts are held together by a ring made of a metal strip of cross sectional area S and length L. L is slightly less than 2piR . To fit the ring on the wheel, it is heated so that its temperature rises by DeltaT and it just steps over the wheel. As it cools down to surrounding temperature, it process the semicircle parts together. If the coefficient of linear expansion of the metal is alpha , and it Young's modulus is Y, the force that one part of the wheel applies on the other part is :
