Question

Bending stress on the neutral axis of the cross sectional beam is _________

• A. Maximum
• B. Minimum
• C. Zero
• D. Infinity

Answer 1

Answer:

C. Zero

The bending stress on the neutral axis of a cross-sectional beam is zero. This is because the layer of fibers in between is neither in tension nor compression. The neutral axis is an axis where there are no longitudinal stresses or strains. Shear stress is non-zero and mostly maximum along the neutral axis.
