Calculate the maximum bending moments in the beam?

The maximum bending moment is located at the point where shear is zero. This occurs because shear is the mathematical derivative of bending moment, and the maximum bending moment occurs when its derivative (i.e. Shear) is zero.


What is the difference between deflection and bending?

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.


What is the significance of the point of contra flexure?

A point of contra flexure occurs where the bending moment in a beam changes its sign (i.e. from +ve to -ve or -ve to +ve) So, obviously at the point of contraflexure the bending moment is zero. But note that the bending moment can be zero without changing its sign. So, at the point of contraflexure the bending moment has to be zero and the bending moment must change its sign as well.


What will be the shear force when bending moment is constant?

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.

Why is the maximum bending moment of a structural member as the point of zero shear?

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.

What is Point of contraflexure?

Point of contraflexure(POC) is a point in the bending moment diagram where bending moment changes its sign.. ie from +ve to -ve or vise versa...by this we can come to a conclusion that POC is a point where bending moment is zero. - K @ $ ! civil engineering.. GITAM UNIVERSITY
