When designing for dynamic loading, the Goodman line is used to predict fatigue failure by accounting for both mean and alternating stresses. The Goodman line is best described as:
- 1A horizontal line in the mean stress versus alternating stress plot
- 2A parabolic curve in the mean stress versus alternating stress plot
- 3A vertical line in the mean stress versus alternating stress plot
- 4A linearly decreasing line in the mean stress versus alternating stress plot✓
Correct answer
A linearly decreasing line in the mean stress versus alternating stress plot
