In a theory it states that beam linear before application of load (self weight is neglected) so linear is correct.

Here no act loading in this beam so the corect answer is Linear (here self weight of the beam are no prefer).

If self with neglected then answer will be linear.

But if self with include answer will be parabola.

In some portion, self wg of member is not considered in calculation so given answer is right.

dM/dX = F.
dF/dX = w =0, shear variation is rectangle shape x^0.
So, BMD Varn is linear.

I think answer is parabola. Self weight of beam is always acts as UDL.

Belkeri shivakumar said:   8 years ago
Linear is correct. No any load sfd is rectangular than bm is linear.

Vinay said:   1 decade ago
Yes I agree it is parabola since the dead load of the beam is UDL.

@All.

No, parabola is not a correct answer. Linear is correct.

Prasanth said:   7 years ago
Answer is linear. There is no external load Hence it is liner.
