A uniform elastic rod of cross-section area \(A\), natural length \(L\) and Young's modulus \(Y\) is placed on a smooth horizontal surface. Now two horizontal forces (of magnitude \(F\,{\text{and}}\,3\;F\) ) directed along the length of rod and in opposite direction act at two of its ends as shown. After the rod has acquired steady state, the extension of the rod will be
369826 A metal bar of length \(L\) and area of cross section A is clamped between two rigid supports. For the material of the rod, its Young's modulus is Y and coefficient of linear expansion is \(\alpha\). If the the temperature of the rod increased by \(\Delta t^\circ {\text{ }}C\), the force exerted by the rod on the supports is
