Question

If the shear force at a section of a beam under bending is equal to zero then the Bending moment at the section is

• A. Zero
• B. Max.
• C. Min.
• D. Max./Min.

Answer 1

The correct option is D Max./Min.

$V=\frac{dM}{dx}$

$V\to$ Shear force

$M\to$ Moment

$\therefore$ $\frac{dM}{dx}=0$

Which implies that BM has a maxima or minima at that section.
