Rigid pipe (2) is supported by a pin connection at C and tie rod (1). The structure supports a load P = 11 kN at pin B. Assume x1 = 3.5 m, x2 = 1.7 m, and y1 = 4.3 m. Determine the force in tie rod (1).

The rigid beam BC is supported by rods (1) and (2). For a uniformly distributed load of w = 3.4 kN/m, determine the force in rod (1). Assume a = 3.40 m and L = 5.60 m.

Before an automotive engine is started, its timing belt has a length of 39.00 in. and a temperature of 70°F. At the engine operating temperature of 200°F, it is determined that the belt has elongated to 39.04 in. What is the coefficient of thermal expansion of the belt?

A short column is loaded in compression. Segment (1) has a solid cross section with a diameter of 1.20 in. Segment (2) is hollow with an outside diameter of 1.44 in. and a wall thickness of 0.12 in. If segment (2) has a normal stress of 19 ksi, determine the normal stress in segment (1).

A short column is loaded in compression. Segment (1) has a solid cross section with a diameter of 1.30 in. Segment (2) is hollow with an outside diameter of 1.54 in. and a wall thickness of 0.12 in. If segment (2) has a normal stress of 19 ksi, determine the normal stress in segment (1).

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 100 mm and the height is 190 mm. The size of the bearing plate is 112 mm. Determine the bearing stress between the plate and the beam.

A steel [E = 215 GPa, ν = 0.317] rod with a circular cross section is used as a weight hanger. The straight part of the rod is 145-mm long and has a diameter of 4.8 mm. Determine the magnitude of the lateral strain in this portion of the rod when it supports a tensile load of 12.0 N.

Discuss the limitations and potential ethical concerns of suspect-based profiling, including the risk of racial or ethnic bias.

Threat assessment evaluates the seriousness of a known threat, whereas risk assessment estimates the likelihood of future harm.

The technique that uses crime locations to determine an offender’s likely residence or base of operations is called __________ profiling.
