bending force is the amount of energy it takes to compromise the item from its natural shape or condition

A bending force is a combination of tension and compression.

Take a beam as an example. Moment is responsible for a beam to rotate about some axis. Whereas bending moment are a pair of moments which will not rotate the beam but it will deflect it.

Sagging bending moment causes the beam to bend in a way to make concavity downward (cup-shaped) and it results in developing tensile stress in lower half of the beam x-section.

It is the maximum stress at which a material will fail when subject to flexural ( moment producing) bending loads. These stresses occur a the material outer fibers.

mass moment of inertia is the property of the body to resist rotation about the given axis where as the area moment of inertia is the resistance to bending about the given axis

in strength of material, u studied shear force and bending moment diagram for static load ( load position is fixed) but influence line diagram is used to draw shear force diagram and bending moment diagram for moving load (load position varies with distance)..

MAXIMUM SHEAR force bending moment is zero shear force change inside is called bending moment

Bending moment With "bending" you really mean the bending moment. The bending moment in an inner stress within a member (usually beam) that allows it to carry a load. The bending moment doesn't say anything about how much a beam would actually bend (deflect). Deflection Deflection measures the actual change in a material you could call "bending." It measures the physical displacement of a member under a load.

On SFD's and BMD's: The shear force will be 0, the shear force is the derivative of the bending moment at a point on shear force and bending moment diagrams. Otherwise: It depends on the loading.

when a moment is applied in a structure the element bend

The importance of shear force and bending moment diagram in mechanics lies in structural design and in deflection of beams.

Shear is the rate at which bending moment changes or shear is its derivative with respect to span. The integral, bending moment, goes through a maximum when shear goes from positive to negative or vice-versa.

Shear Force: Sum of all Vertical Forces Whose acting on a Beam but Sum of all vertical Forces must be equal to Zero. Bending Moment: The Product of Force And Displacement is known as Bending moment.
