Axial loads are applied with rigid bearing plates to the solid cylindrical rods. One load of P = 120 kN is applied to the assembly at A, two loads Q = 20 kN are applied at B, and two loads R = 170 kN are applied at C. Determine the total change in length of the assembly.L1 = 0.28 m, E1 = 192 GPa, A1 = 0.0012 m2L2 = 0.42 m, E2 = 210 GPa, A2 = 0.0005 m2L3 = 0.38 m, E3 = 108 GPa, A3 = 0.0015 m2

A steel [E = 200 GPa; ν = 0.3; α = 10.9 ×10-6/°C] plate has a rectangular hole at its center and four circular holes at the corners. At an initial temperature of Ti = –16°C, the plate is 85 mm wide, 140 mm long, and 13 mm thick. The rectangular hole is 25 mm wide and 75 mm long. The circular holes have a diameter of 25 mm. At a final temperature of Tf = 48°C, determine the length of the rectangular hole.
