Question

A propped cantilever of uniform flexural rigidity is loaded as shown in the given figure. The bending moment at fixed end A is

• A. 150 kN-m sagging
• B. 150 kN-m hogging
• C. 300 kN-m sagging
• D. 300 kN-m hogging

Answer 1

The correct option is B 150 kN-m hogging


The moment is transferred to point B directly.

$\text{If}{M}_{BA}=300\text{kN-m}$

$M_{AB}=\frac{1}{2}\times 300=150\text{kN-m}$
$\text{As the carry over factor for beam is}\frac{1}{2}.$
$\text{The direction of moment will be anticlockwise i.e. hogging.}$
