When analyzing a beam under bending, where do complementary stresses typically occur?

39. When analyzing a beam under bending, where do complementary stresses typically occur?

1. At the points of maximum bending
2. Along the neutral axis
3. At the centroid of the beam
4. Throughout the entire cross-section uniformly

Answer

The correct answer is: B) Along the neutral axis

Explanation

In a bending beam, complementary stresses occur along the neutral axis, where the stress neutralizes the bending moment instead of being tensile or compressive.
