Problem 1. Concentrated load P. at B and difference AT(x) are applied to circular bar with Young's Modulus E and thermal expansion coefficient ar. The diameter of segment AB varies linearly from D at A to 2D at B. The temperature difference AT(x) is applied to segment BC. (a) Find the reaction forces at A and C. (b) Find the deflection of point B. E, a 2D DI Po A B C L AT (x) = To To
