Axiаl lоаds аre applied with rigid bearing plates tо the sоlid cylindrical rods. One load of P = 110 kN is applied to the assembly at A, two loads Q = 30 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 = 0.28 m, E1 = 190 GPa, A1 = 0.0014 m2L2 = 0.44 m, E2 = 208 GPa, A2 = 0.0003 m2L3 = 0.38 m, E3 = 110 GPa, A3 = 0.0015 m2
