A short column is loaded in compression. Segment (1) has a solid cross section with a diameter of 1.00 in. Segment (2) is hollow with an outside diameter of 1.24 in. and a wall thickness of 0.12 in. If segment (2) has a normal stress of 16 ksi, determine the normal stress in segment (1).

Axial loads are applied with rigid bearing plates to the solid cylindrical rods shown. If F1 = 30 kips, F2 = 19 kips, F3 = 23 kips, and F4 = 37 kips, determine the absolute value of the axial load in rod (2).

A steel rod with a circular cross section is used as a weight hanger. The straight part of the rod is 165-mm long and has a diameter of 4.4 mm. Determine the longitudinal strain in this portion of the rod when it supports a tensile load of 9.8 N.

Two plates are connected with four bolts and transmit load P = 6.2 kN. Each plate is 5.7 mm thick, and each bolt has a diameter of 11.0 mm. Determine the average shear stress in the bolts.

Two plates are connected with four bolts and transmit load P = 7.2 kN. Each plate is 5.5 mm thick, and each bolt has a diameter of 10.6 mm. Determine the average shear stress in the bolts.

Which of the following is true about fault induction attacks?

A square that was initially a x a in size is deformed into the following shape. If a = 26 mm, b = 7.1 mm, and c = 25 mm, determine the magnitude of the shear strain at C. (Use the small-angle approximation sin γ ≈ tan γ ≈ γ.)

Two plates are connected with two bolts and transmit load P = 4.4 kN. Each plate is 6.0 mm thick, and each bolt has a diameter of 9.5 mm. Determine the average shear stress in the bolts.

Which theory describes the formation of solar systems? 

An engineer is designing a new pulley and shaft assembly that utilizes a square key. Assuming each of the three keys would experience the same shear force, which key would have the largest average shear stress?
