The bar has a cross-sectional area A, length L, modulus of elasticity E, and coefficient of thermal expansion a. The temperature of the bar changes uniformly along its length from T_Aat A to T_Bat B so that at any point x along the bar T = T_A+ x(T_B€“ T_A)/L. Determine the force the bar exerts on the rigid walls. Initially no axial force is in the bar and the bar has a temperature of T_A.
