A 20 mm ø steel rod of weight 5 kN is inserted between two walls 1.5 m apart as shown. Initially, the rod fits between the walls. What minimum temperature increase is required to maintain equilibrium in the system? The coefficient of static friction between the walls and the rod is 0.20. For steel, E = 200 GPa and α = 12 x 10-6/°C
