Question

If the shear force along a section of a beam is zero then bending moment is

Answer 1

When shear force along a section of a beam is zero then the bending moment is either maximum or minimum.

Explanation

• In the zone where the shear force diagram changes from positive to negative, there is a high possibility of getting a maximum bending moment.
• In the zone where the shear force diagram changes from negative to positive, there is a high possibility of getting a minimum bending moment.

Answer 2

Answer:

The bending moment is either maximum or minimum when the shear force along a section of a beam is zero.

Explanation:

• There is a good chance of attaining a maximum bending moment in the zone where the shear force diagram shifts from positive to negative.
• There is a good chance of attaining a minimum bending moment in the zone where the shear force diagram shifts from negative to positive.
