If the double-shear pin at D has a diameter of 0.575 in., an allowable shear strength of 20 ksi, and a factor of safety of 2.1, determine the maximum load P that can be applied to beam ABC. Let a = 34 in., b = 12 in., and c = 9 in.

A short column is composed of two steel segments, each with a length of 4.9 in. Segment (1) is hollow with an outside diameter of 1.30 in. and a wall thickness of 0.16 in. Segment (2) is hollow with an outside diameter of 1.62 in. and a wall thickness of 0.16 in. How much shorter does the column become after a load of P = 870 lb is applied?

A load of P = 355 lb is applied to beam ABC. Bar (1) has a square cross section with a width of 0.89 in. If the normal stress in bar (1) is limited to 10 ksi, determine the factor of safety for bar (1). Let a = 39 in., b = 12 in., and c = 9 in.

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 = 20 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 = 0.26 m, E1 = 192 GPa, A1 = 0.0012 m2L2 = 0.40 m, E2 = 210 GPa, A2 = 0.0005 m2L3 = 0.36 m, E3 = 104 GPa, A3 = 0.0016 m2

A steel rod with a circular cross section is used as a weight hanger. The straight part of the rod is 160 mm long. Determine the minimum diameter D required if this portion of the rod must hold a tensile load of 9.8 N without stretching more than 0.00470 mm.

A 3D printed polymer rod measures 120.00 mm in length while on the heated print bed at 68.3°C. After cooling to room temperature at 22.0°C the rod measures 119.62 mm in length. Determine the coefficient of thermal expansion of the polymer.
