Yes, @Syed Irfan.

My argument is also that only.

At the max BM SF will be zero. Not possible reverse side like where SF is zero BM is max.

If In a cantilever beam, At free end doesn't any load whereas fs is zero and bmd must be zero. How you say that, Will you please explain?

Syed irfan said:   8 years ago
No, it will not be maximum because bending moment is maximum at a point where shear force is zero only at a point not along the section.

Since dM/dx = V.

So when V (shear force) = 0, => dM/dx = 0 means M can be maximum or minimum.

How is the answer maximum ?

Numerically we can't get the maximum value we have to see the loading condition.

Well said @Abdul Samad.

The right answer is either maximum or minimum.

When shear force zero at the time only we have maximum bending moment.

Shear force is zero, i.e Result BM either max or min n.

Mahesh said:   9 years ago
Shear force is Zero then maximum B.M is applied.

Answer is maximum or minimum? Please explain.
