______ is a term used to describe crimes that go unreported.

A load of 15 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 74 mm and the height is 140 mm. The size of the bearing plate is 94 mm. Determine the bearing stress between the plate and the beam.

If μ = 37 and σ = 7, what is Pr{Y > 37} ? (Hint, you don’t need tables – draw a picture and you should have the answer right away).

Before an automotive engine is started, its timing belt has a length of 43.00 in. and a temperature of 70°F. At the engine operating temperature of 210°F, it is determined that the belt has elongated to 43.04 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 = 19 kN at pin B. Assume x1 = 3.2 m, x2 = 1.7 m, and y1 = 3.2 m. Determine the force in tie rod (1).

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 1.26 in. and a wall thickness of 0.13 in. If segment (2) has a normal stress of 10 ksi, determine the normal stress in segment (1).

Before an automotive engine is started, its timing belt has a length of 45.00 in. and a temperature of 60°F. At the engine operating temperature of 195°F, it is determined that the belt has elongated to 45.04 in. What is the coefficient of thermal expansion of the belt?
