A 3D printed polymer rod measures 157.00 mm in length while on the heated print bed at 55.7°C. After cooling to room temperature at 20.5°C the rod measures 156.52 mm in length. Determine the coefficient of thermal expansion of the polymer.

If the normal stress in rod (1) is limited to 250 MPa and the required factor of safety is 2.0, determine the maximum load P that can be applied to rod (2). Let a = 0.32 m, b = 0.73 m, and the cross-sectional area of rod (1) be 115 mm2.

If a load of P = 18 kN is applied to rod (2), determine the magnitude of the resultant force at C. Let a = 0.41 m and b = 0.71 m.

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).
