The variation of bending moment due to uniformly distributed load is​

Answer 1

Answer:

Case III Bending moment due to uniformly varying load

Bending moment due to a varying load is equal to the area of load diagram x distance of its centroid from the point of moment. The shape of bending moment diagram due to a uniformly varying load is a cubic parabola.

Answer 2

The variation of bending moment due to uniformly distributed load is given by parabolic law.

• The area of the load diagram x the distance of its centroid from the point of moment equals the bending moment due to a variable load.

• A cubic parabola is the geometry of a bending moment diagram due to a uniformly fluctuating load.
• A uniform distributed load is a force that is evenly distributed across the length of a support. This load is dispersed along the whole length of the support for the least amount of deflection possible. A shipment crate on a forklift is an example.
