A load of P = 260 lb is applied to beam ABC. Bar (1) has a square cross section with a width of 0.97 in. If the normal stress in bar (1) is limited to 10 ksi, determine the factor of safety for bar (1). Let a = 38 in., b = 14 in., and c = 11 in.

A 3D printed polymer rod measures 142.00 mm in length while on the heated print bed at 58.5°C. After cooling to room temperature at 20.8°C the rod measures 141.53 mm in length. Determine the coefficient of thermal expansion of the polymer.

A steel [E = 185 GPa] 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 0.00590 mm.

Stella’s Bakery calculated their net income to be $450,000 before any adjusting journal entries were recorded.  What amount of net income will Stella’s Bakery report after adjusting journal entries are recorded for the following transactions: Earned $25,000 of service revenue that was initially recorded as unearned Depreciated $5,000 for equipment

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 = 140 kN are applied at C.
