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?

A behavior analyst is working on toilet training with several clients, all focused on the target behavior of appropriate eliminations. The behavior is difficult to reverse, and the parents of each client request that treatment not be removed to a return to baseline but are fine with an initial extended baseline.  Which experimental design would be most appropriate for the behavior analyst to use?

Herman wants to achieve a healthy weight and lifestyle. Since Herman works from home, he creates an indoor gym in a spare room. For the first week after creating his at-home gym, Herman plans to exercise for 30 minutes each day. For the second week, he wants to increase his exercise time to 40 minutes per day. He will continue to increase the time spent exercising for 5 minutes longer each week until he meets his goal weight. Given this scenario, which of the following is a short-term objective?

______ is a term used to describe crimes that go unreported.
