Question: Suppose that we would like a part produced from the acetal polymer shown in Figure 7-27 to survive for one million cycles under conditions that

Suppose that we would like a part produced from the acetal polymer shown in Figure 7-27 to survive for one million cycles under conditions that provide for equal compressive and tensile stresses. What is the fatigue strength, or maximum stress amplitude, required? What are the maximum stress, the minimum stress, and the mean stress on the part during its use? What effect would the frequency of the stress application have on your answers? Explain.
