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 = 40 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 = 0.24 m, E1 = 194 GPa, A1 = 0.0014 m2L2 = 0.46 m, E2 = 208 GPa, A2 = 0.0005 m2L3 = 0.34 m, E3 = 106 GPa, A3 = 0.0015 m2

A force of P = 25 N is applied to a lever at the end of a composite shaft. Sleeve (1) has a polar moment of inertia of 128,000 mm4 and a shear modulus of 1.9 GPa. Core (2) has a polar moment of inertia of 19,100 mm4 and a shear modulus of 1.3 GPa. Determine the torque produced in core (2). Let a = b = 215 mm.
