Question

A uniformly distributed load(w) of length shorter than the span crosses a girder. The bending moment at a section in girder will be maximum when

• A. Head of the load is at the section
• B. Section divides the load in the same ratio as it divides the span
• C. Section divides the load in two equal lengths
• D. Tail of the load is at the section

Answer 1

The correct option is B Section divides the load in the same ratio as it divides the span



For maximum bending moment at section C

$\frac{a}{b}=\frac{x}{l-x}$
