Tell me one thing please when you neglect self-weight than without external loading which type of load acting on the beam so bending moment in the beam is linear?
So, the correct answer is parabolic.
So, the correct answer is parabolic.

Beams with no external loads are considered as 2D. Therefore, self-weight is not considered. Hence the shape will be linear.

Answer is linear. There is no external load Hence it is liner.

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

Linear is correct. No any load sfd is rectangular than bm is linear.

Yes. You people first read the question. All of said linear is satisfactory if without consider dead loads. If it considers parabola is correct.

Yes, linear is the correct answer.

Yes, linear is the correct answer since there is no point or UDLload acting on the beam and the self-weight of the beam is neglected.

Here there is no load acting on the beam.
So there is no upward force and downward force on the beam (self-weight is neglected) so BM variation is "Zeo (0) ".

We know that self-weight is UDL and UDL BM is parabola.
Here, the answer is the parabola (when self-weight should be considered) or it must be linear (when self-weight should not be considered).
