A steel [E = 215 GPa, ν = 0.298] rod with a circular cross section is used as a weight hanger. The straight part of the rod is 135-mm long and has a diameter of 5.0 mm. Determine the magnitude of the lateral strain in this portion of the rod when it supports a tensile load of 9.8 N.

A square that was initially a x a in size is deformed into the following shape. If a = 24 mm, b = 12 mm, and c = 21 mm, determine the magnitude of the shear strain at A. (Use the small-angle approximation sin γ ≈ tan γ ≈ γ.)

A steel [E = 190 GPa, ν = 0.250] rod with a circular cross section is used as a weight hanger. The straight part of the rod is 170-mm long and has a diameter of 4.6 mm. Determine the magnitude of the lateral strain in this portion of the rod when it supports a tensile load of 8.8 N.

A load of 12 kN is applied through a pin connection and a square bearing plate to the end of a beam that has a rectangular cross section. The base of the beam’s cross section is 68 mm and the height is 200 mm. The size of the bearing plate is 88 mm. Determine the bearing stress between the plate and the beam.

What should you do if you spill a bacterial culture on the lab bench?

A short column is loaded in compression. Segment (1) has a solid cross section with a diameter of 1.10 in. Segment (2) is hollow with an outside diameter of 1.50 in. and a wall thickness of 0.20 in. If segment (2) has a normal stress of 17 ksi, determine the normal stress in segment (1).

A square that was initially a x a in size is deformed into the following shape. If a = 21 mm, b = 6.4 mm, and c = 20 mm, determine the magnitude of the shear strain at B. (Use the small-angle approximation sin γ ≈ tan γ ≈ γ.)

Before an automotive engine is started, its timing belt has a length of 41.00 in. and a temperature of 60°F. At the engine operating temperature of 210°F, it is determined that the belt has elongated to 41.04 in. What is the coefficient of thermal expansion of the belt?

Rigid pipe (2) is supported by a pin connection at C and tie rod (1). The structure supports a load P = 20 kN at pin B. Assume x1 = 3.6 m, x2 = 1.1 m, and y1 = 4.4 m. Determine the force in tie rod (1).
