Question

If the shear force line is a cubic curve between any two points

Answer 1

7-For any part of the beam, between two concentrated load Shear force diagram is a. Horizontal straight line; Vertical  ...

Answer 2

If the shear force line is a cubic curve between any two points:

• If the load between two places is uniformly variable, the shear force varies according to the parabolic law (i.e. the shear force line is a parabola), whereas the bending moment changes according to the cubic law.
• When shear force changes, it indicates that the bending moment is at its peak.
