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 1.24 in. and a wall thickness of 0.12 in. If segment (2) has a normal stress of 11 ksi, determine the normal stress in segment (1).

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?

A steel rod with a circular cross section is used as a weight hanger. The straight part of the rod is 150-mm long and has a diameter of 5.0 mm. Determine the longitudinal strain in this portion of the rod when it supports a tensile load of 9.8 N.

Three rubber bands are shown before and after being stretched. Before stretching, bands A, B and C have lengths of 85 mm, 120 mm, and 165 mm, respectively. After stretching, band A has a length of 95 mm, while bands B and C each have a length of 190 mm. Determine the maximum normal strain in the bands.
