Physics · Strength of Materials
When a beam/shaft is subjected to pure bending moment such that the material stays within its elastic limit, the induced stress distribution is:
- 1Uniform normal axial stress throughout the cross-section
- 2Torsional shear stress varying parabolic along the shaft surface
- 3Bending stress that varies linearly with distance from the neutral axis✓
- 4Pure shear stress uniformly distributed across the full cross-section
Correct answer
Bending stress that varies linearly with distance from the neutral axis
