Question

The magnitude of maximum bending moment developed at 'E' for the doubly overhanging beam (as shown) when two concentrated loads of 100 kN each, 3m apart crosses the beam from left to right is

• A. 200 kN-m
• B. 55.56 kN-m
• C. 166.67 kN-m
• D. 100 kN-m

Answer 1

The correct option is C 166.67 kN-m

Let us first of all draw ILD for moment at E

Bending moment will be maximum, when the 100 kN load is at E and other one is 3m right side of it.

$\therefore (M_E{)}_{max}=100\times \frac{4}{3}+100\times \frac{1}{3}=166.67kN-m$

Hence, option (B).
