Question

The bending moment at a section of a beam will have its local maximum where the shear force is-

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

Answer 1

Answer:

C. Zero

The bending moment of a beam has its maximum value where the shear force is zero. This is because the rate of change of bending moment is equal to the shear force. The maximum and minimum values of bending moment occur where the slope of the bending moment distribution is zero.
