Detailed Solution for Test: Bending Moment & Shear Force Diagram - 1 - Question 12

Uniformly distributed load on cantilever beam.

Test: Bending Moment & Shear Force Diagram - 1 - Question 13

A vertical hanging bar of length L and weighing w N/ unit length carries a load W at the bottom. The tensile force in the bar at a distance Y from the support will be given by

Test: Bending Moment & Shear Force Diagram - 1 - Question 14

Assertion (A): If the bending moment along the length of a beam is constant, then the beam cross section will not experience any shear stress.

Reason (R): The shear force acting on the beam will be zero everywhere along the length.

Test: Bending Moment & Shear Force Diagram - 1 - Question 15

What is the bending moment at end supports of a simply supported beam?

Detailed Solution for Test: Bending Moment & Shear Force Diagram - 1 - Question 15

At the end supports, the moment (couple) developed is zero, because there is no distance to take the perpendicular acting load. As the distance is zero, the moment is obviously zero.
