A 3D printer is used to create a shock absorbed composed of two polymers. Polymer (1) [E = 260 ksi] has a cross-sectional area of 2.0 in.2. Polymer (2) [E = 220 ksi] has a cross-sectional area of 2.0 in.2. After the shock absorber is loaded between steel plates by load P = 500 lb, determine the load carried by polymer (2).
