The bar has a cross-sectional area A, length L, modulus of elasticity E, and coefficient
Chapter 4, Problem 4-77(choose chapter or problem)
The bar has a cross-sectional area A, length L, modulus of elasticity E, and coefficient of thermal expansion \(\alpha\). The temperature of the bar changes uniformly along its length from \(T_{A}\) at A to \(T_{B}\) at B so that at any point x along the bar \(T=T_{A}+x\left(T_{B}-T_{A}\right) / L\). 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 \(T_{A}\).
