Question

A simply supported beam is loaded as shown in the given figure. The bending moment at E would be

• A. 6 t-m (Sagging)
• B. 4 t-m (Hogging)
• C. 6 t-m (Hogging)
• D. 4 t-m (Sagging)

Answer 1

The correct option is D 4 t-m (Sagging)

(d)
Reaction at A,
$R_A=\frac{2\times 1+4\times 2+2\times 3}{4}=4t$

$R_B=4t$
$\therefore BendingmomentatE,$
$M_E=-2+4\times 2-2\times 1$
= 4 t-m (sagging)
