The components of the reaction at A are: Ax = lb- Ay = lb t The components of the reaction at E are: E₁= lb→

(ii) 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 T₁ at A to T at B so that at any point x along the bar T = T₁ + x(T-TA)/L. Determine the force the bar exerts on the rigid walls. Initially the bar has a temperature of TA A A в
