A solid brass [E = 98 GPa] axial member is loaded and supported as shown. Segments (1) and (2) each have a diameter of 20 mm and segment (3) has a diameter of 15 mm. Assume L1 = 1.8 m, L2 = 1.2 m, L3 = 1.5 m, R = 38 kN, Q = 12 kN, and P = 22 kN. Determine: (a) the deformation of segment (2). (b) the deflection of joint D with respect to the fixed support at A. (c) the maximum normal stress in the entire axial member.
