Axial loads are applied with rigid bearing plates to the solid cylindrical rods. One load of P = 130 kN is applied to the assembly at A, two loads Q = 40 kN are applied at B, and two loads R = 140 kN are applied at C. Determine the total change in length of the assembly.L1 = 0.22 m, E1 = 196 GPa, A1 = 0.0014 m2L2 = 0.44 m, E2 = 200 GPa, A2 = 0.0004 m2L3 = 0.36 m, E3 = 110 GPa, A3 = 0.0015 m2

A 3D printed polymer rod measures 193.00 mm in length while on the heated print bed at 67.1°C. After cooling to room temperature at 22.0°C the rod measures 192.36 mm in length. Determine the coefficient of thermal expansion of the polymer.

If the length of a timber [E = 1,700 ksi] column cannot change by more than 0.020 in., determine the maximum load P that can be applied to the column. Let b = 5.00 in., d = 8.50 in., and L = 98 in.

A load of P = 14,900 lb is applied to the connection. If the average shear stress in the bolts is limited to 34 ksi and the required factor of safety is 2.3, determine the minimum allowable bolt diameter.

Axial loads are applied with rigid bearing plates to the solid cylindrical rods. One load of P = 100 kN is applied to the assembly at A, two loads Q = 40 kN are applied at B, and two loads R = 160 kN are applied at C.

A 3D printer is used to create a shock absorbed composed of two polymers. Polymer (1) [E = 240 ksi] has a cross-sectional area of 2.0 in.2. Polymer (2) [E = 200 ksi] has a cross-sectional area of 2.0 in.2. After the shock absorber is loaded between steel plates by load P = 820 lb, determine the load carried by polymer (1).
