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?

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 70 mm and the height is 180 mm. The size of the bearing plate is 82 mm. Determine the bearing stress between the plate and the beam.

You want to have $87,000 in 16 years to help your child attend college. If you can earn an annual interest rate of 4.3 percent, how much will you have to deposit today?

A steel 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 4.2 mm. Determine the magnitude of the lateral strain in this portion of the rod when it supports a tensile load of 11.0 N.

____________ tissue is similar to osseous in function. However, it somewhat more flexible.

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 72 mm and the height is 160 mm. The size of the bearing plate is 92 mm. Determine the bearing stress between the plate and the beam.

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.
