If you consider till left side it will be 0 only.

SF@L = wl/2-wl/2 = 0.
SF@R = wl/2-wl = wl/2.

As wl/2 is not given in the option, the answer should be 0.
So, the given answer is correct.

We will get an answer from the shear force diagram.

It's WL/2.

How Can Say Zero is the right answer?

The point of inflexion lies at the centre of the beam in this case. So, it is the right answer.

Neeraj said:   9 years ago
Answer is right it asks at centre of the beam that is l/2, not at x=0 at x=0 WL/2.

It has to be (Wl)/2.

Where shear force minimum it has Max bending momentum.

Vijay said:   9 years ago
It should be wl/2.
