Part 4. Problems (20 points, 10 points each)

____________ 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.

A steel rod with a circular cross section is used as a weight hanger. The straight part of the rod is 170-mm long and has a diameter of 4.0 mm. Determine the magnitude of the lateral strain in this portion of the rod when it supports a tensile load of 12.0 N.

Three rubber bands are shown before and after being stretched. Before stretching, bands A, B and C have lengths of 75 mm, 115 mm, and 150 mm, respectively. After stretching, band A has a length of 90 mm, while bands B and C each have a length of 180 mm. Determine the maximum normal strain in the bands.

A square that was initially a x a in size is deformed into the following shape. If a = 25 mm, b = 9.8 mm, and c = 23 mm, determine the magnitude of the shear strain at C. (Use the small-angle approximation sin γ ≈ tan γ ≈ γ.)

Two plates are connected with four bolts and transmit load P = 5.2 kN. Each plate is 4.2 mm thick, and each bolt has a diameter of 10.2 mm. Determine the average shear stress in the bolts.

Robert is an adult with autism who works at a plant workshop, taking care of the plants in the small nursery. Robert often struggles with staying on task for longer periods of time while at the workshop, so his behavior analyst wants to use a token system to increase the duration of Robert’s on-task behavior. The behavior analyst identifies certain items that Robert is likely to work to earn and places these items in the token store at the workshop. On some nights, Robert’s roommate at his group home stays awake late at night, making loud noises and deprives Robert of a good night’s sleep.  On the days that follow a bad night’s sleep, Robert is much less likely to stay on task at work, even if his most highly preferred items are in the token store. Which of the following is most likely an example of history effects in this scenario?

You want to have $12,500 in 10 years for a dream vacation. If you can earn an interest rate of .3 percent per month, how much will you have to deposit today?
