A wooden wheel of radius \(R\) is made of two semicircular part (see figure). The two parts are held together by ring made of a metal strip cross sectional area \(A\) and length \(L\). \(L\) is slightly less than \(2 \pi R\). To fit the ring on the wheel, it is heated so that its temperature rises by \(\Delta T\) and it just steps over the wheel. As it cools down to surrounding temperature, it presses the semicircular parts together. If the cofficient of linear eaxpansion of the metal is \(\alpha\), and its Young's modulus is Y, the force that one part of the wheel applies on the other part is:
