Axial loads are applied with rigid bearing plates to the solid cylindrical rods. One load of P = 90 kN is applied to the assembly at A, two loads Q = 50 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 = 196 GPa, A1 = 0.0012 m2L2 = 0.40 m, E2 = 212 GPa, A2 = 0.0004 m2L3 = 0.36 m, E3 = 108 GPa, A3 = 0.0016 m2

A 3D printer is used to create a shock absorbed composed of two polymers. Polymer (1) [E = 200 ksi] has a cross-sectional area of 1.2 in.2. Polymer (2) [E = 280 ksi] has a cross-sectional area of 1.2 in.2. After the shock absorber is loaded between steel plates by load P = 575 lb, determine the load carried by polymer (1).
