Axiаl lоаds аre applied with rigid bearing plates tо the sоlid cylindrical rods. One load of P = 90 kN is applied to the assembly at A, two loads Q = 20 kN are applied at B, and two loads R = 150 kN are applied at C. Determine the total change in length of the assembly.L1 = 0.26 m, E1 = 192 GPa, A1 = 0.0012 m2L2 = 0.40 m, E2 = 210 GPa, A2 = 0.0005 m2L3 = 0.36 m, E3 = 104 GPa, A3 = 0.0016 m2
