Question

Describe the relationships between load, shear force, and bending moment.

Answer 1

Answer:

the relation between load , shear force and bending moment is

shear force in a beam is calculated by the differentiation of the loading with respect to distance or length of the beam

                                           $V = \dfrac{dw}{dx}$

Bending moment in a beam is define as the change of shear force diagram with respect to the length of the beam.

                                           $M = \dfrac{dV}{dx}$

     and where as               $M = \dfrac{d^2w}{dx^2}$  

where V is the shear force , x is the distance in the beam , M is the bending moment and w is the loading on the beam.
