A load of 13 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 76 mm and the height is 170 mm. The size of the bearing plate is 86 mm. Determine the bearing stress between the plate and the beam.

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).

Before an automotive engine is started, its timing belt has a length of 38.00 in. and a temperature of 60°F. At the engine operating temperature of 220°F, it is determined that the belt has elongated to 38.04 in. What is the coefficient of thermal expansion of the belt?

[FinB] Malina wants to improve the performance of the assembly line worker she manages. Currently, the worker produces an average of 500 units per day in baseline. Malina first implements a feedback system where she posts the worker’s daily productivity. Almost immediately after the feedback system’s implementation, productivity increases to an average of 750 units per day. After 2 weeks at this level, Malina implements a pay-for-performance system with bonuses based on productivity rates. This performance system produces an average of 1,000 units per day for the next 2 weeks. Malina continues implementing these interventions in this same order without randomization and sees similar behavior patterns. Later, Malina implements the performance system immediately following the 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?

Two plates are connected with four bolts and transmit load P = 5.9 kN. Each plate is 6.0 mm thick, and each bolt has a diameter of 10.8 mm. Determine the average shear stress in the bolts.

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.

The hydrologic cycle (or water cycle) is driven by energy from the Sun. This is an example of ____________.

Two plates are connected with four bolts and transmit load P = 6.9 kN. Each plate is 4.0 mm thick, and each bolt has a diameter of 9.1 mm. Determine the average shear stress in the bolts.
