The beam AB has a moment of inertia , and rests on the smooth supports at its ends. A 50 mm in diameter post CD is placed at the center of the beam. If the temperature of the rod is increased by 100 °C, determine the force developed in the rod. The beam and rod are both made of steel for which E = 200 GPa and
