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?

The U.S. Constitution used which Enlightenment thinker’s ideas of political checks and balances? 

Harout wants to improve the performance of the assembly line worker he manages. Currently, the worker produces an average of 750 units per day in baseline. Harout first implements a feedback system where he posts graphs representing the worker’s daily number of units produced. Almost immediately after the feedback system’s implementation, productivity increases to an average of 1,000 units per day. After two weeks at this level, Harout decides to implement a pay-for-performance system with bonuses based on productivity rates. This performance system produces an average of 1,200 units per day for the next 2 weeks. Harout continues implementing these interventions in this same order without randomization and sees similar behavior patterns. Later, Harout implements the performance system immediately following baseline and finds that it is not as effective as it had been during the original testing period. The results of these data are most likely being impacted by which confound?
