The beam AB has a moment of inertia I = 475 in⁴and rests on the smooth supports at its ends. A 0.75-in-diameter rod CD is welded to the center of the beam and to the fixed support at D. If the temperature of the rod is decreased by 150°F, determine the force developed in the rod. The beam and rod are both made of steel for which E = 200 GPa and α = 6.5(10^-6) / F^o.
