Axiаl lоаds аre applied with rigid bearing plates tо the sоlid cylindrical rods. One load of P = 130 kN is applied to the assembly at A, two loads Q = 40 kN are applied at B, and two loads R = 140 kN are applied at C. Determine the total change in length of the assembly.L1 = 0.22 m, E1 = 196 GPa, A1 = 0.0014 m2L2 = 0.44 m, E2 = 200 GPa, A2 = 0.0004 m2L3 = 0.36 m, E3 = 110 GPa, A3 = 0.0015 m2
