Question

Which one of the following is the bending moment diagram for the vertical cantilever beam loaded as shown in the figure below?

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

(a)
Moment C = 10 $\times$ 0.3 kN-m anti-clockwise.
There is no change of moment from C to B.
The moment at B = 5 $\times$ 0.6 = 3 kN clockwise
Net moment at in AB = 3-3=0
