As long as mechanical strength is concerned (especially dynamic, i.e. fatigue strength), which kind of residual stresses is beneficial at the surface of mechanical components? Question 28 options: Residual stresses do not influence fatigue strength Compressive No residual stresses are allowed in any of mechanical components The sign of residual stresses is not important, as long as they are present Tensile

A 1.2-lb slider is propelled upward at A along the fixed curved bar which lies in a vertical plane. If the slider is observed to have a speed of 10.2 ft/sec as it passes position B, determine (a) the magnitude N of the force exerted by the fixed rod on the slider and (b) the rate $\dot{v}$ at which the speed of the slider is changing (positive if speeding up, negative if slowing down). Assume that friction is negligible. Answers: $N = 1.365 lb$ $\dot{v} = -19.36 ft/sec^2$

Critical Thinking Challenges The power of a test (1 - ?) can be calculated when a specific value of the mean is hypothesized in the alternative hypothesis; for example, let $H_0: \mu = 50$ and let $H_1: \mu = 52$. To find the power of a test, it is necessary to find the value of ?. This can be done by the following steps: Step 1 For a specific value of ? find the corresponding value of X, using $z = \frac{X - \mu}{\sigma/\sqrt{n}}$ where ? is the hypothesized value given in $H_0$. Use a right-tailed test. Step 2 Using the value of X found in step 1 and the value of ? in the alternative hypothesis, find the area corresponding to z in the formula $z = \frac{X - \mu}{\sigma/\sqrt{n}}$ Step 3 Subtract this area from 0.5000. This is the value of ?. Step 4 Subtract the value of ? from 1. This will give you the power of a test. See Figure 8-41. 8-72 1. Find the power of a test, using the hypotheses given previously and ? = 0.05, ? = 3, and n = 30. FIGURE 8-41 Relationship Among ?, ?, and the Power of a Test Answers to Applying the Concepts 485 2. Select several other values for ? in $H_1$ and compute the power of the test. Generalize the results.

The "mode" is a statistical summary of data (as are min, max, and average) representing the most commonly-occurring value. Given 10 integers ranging from 0 to 99, output the mode and its frequency. If the input is 1111229876, the output is: 1 4 If any integer is outside 0-99, output an error. If an input is 105, the output is: Invalid input: 105 is not in 0-99 Hints: Knowing that integers are in 0-99 enables creating an array with 100 elements to count the occurrences of each value. Traverse the userValues array and keep count by incrementing the appropriate element in a counts array. If the input is 27, then increment element 27's value. While traversing userValues, check for an integer outside the range. If found, print the error message, and immediately return. After done counting, use another loop to traverse the counts array and find the max. Also keep track of the index where max was found.
