Question

The difference in ordinate of the shear curve between any two sections is equal to the area under

Answer 1

In turn, the shear curve is integrated over the length to give the bending moment curve—a ... stress can then be obtained by dividing the maximum bending moment by a beam

Answer 2

Difference in ordinate of the shear curve between any two sections:

Explanation:

• In mechanics, elasticity is the property of a material due to which it undergoes deformation when an external force is applied on it, but it returns to its original position when the force is removed.
• If the magnitude of the external force is gradually increased, the strain increases uniformly, as well as the internal resistance. But if a force is applied on a substance more than a limit, then even after removing that external force, the substance cannot completely return to its original state; Rather, a permanent deformity remains in it.
• This limit of matter is called the limit of elasticity or elastic limit. The minimum force acting on a unit area, bringing a numerically permanent change, is called the "elastic limit".
• The material which has crossed the limit of elasticity is called plastic.
• Within the elastic limit, the strain is proportional to the stress acting on the object. This is an experimental fact and is known as Hooke's law of elasticity.
