The answer can be rectangular only if the question would be, what is the shape of the shear force diagram rather than a bending moment diagram?

Arun chauhan said:   9 years ago
Shear diagram will be rectangular but b, m will be in triangular shape.

Bahaa said:   9 years ago
Having the shear is constant and we have an applied moment of one end, the B.M needs to be of a triangular shape.

Reshu agrawal said:   9 years ago
Yes, the correct answer is a triangle.

Ra + Rb = 0 (because there is no any load).
Bending moment on support b =0.
BM on support A = M (moment).

So, the diagram will be a triangle.

Wrong answer, it should be triangular.

Proof:

Moment at a section x from left end is given by:

M = m-m*(x/l).

m = moment applied at left end.

So at x = 0; M = m.

At x = L; M = 0.

Yes it should be triangular because the moment acting on the support.

It should be triangular.

It can't be rectangular.
