Figure 2 The S-N fatigue curve for an acetal polymer
a. What is the fatigue strength, or maximum stress amplitude, at one million cycles of
loading?
b. An acetal polymer 30-cm-long bar with a diameter of 20 mm is designed to survive
one million cycles of loading, what is the maximum allowable axial load that can be
applied on one end of the bar?
