@Santosini Panda.

If M is constant, then the radius of curvature of the beam is constant and the shape of the elastic curve is a circular arc.

@Santoshi

If R is constant then it is absolutely a circle because the circle is one of figures in which r is constant at any point and direction.

Its a pure bending case where elastic curve is arc of circle.

Tarik said: 5 years ago

It is Parabolic.

Hi,

@Nisar your explanation is right I agree with you. But how it is circle can you please explain.

I think it should be a catenary shape.
