Question

Flexural rigidity of a beam is given by the product of

Answer 1

Answer:

In general case, when the flexural rigidity of a beam B(x) = EI is variable, the theory of such beams reduces to the solution of the differential equation, y • = − M ( x ) B ( x ) . If the loading does not include a distributed bending moment, then M′(x) = -Q(x).

Answer 2

Flexural rigidity of a beam B(x) =EI is variable

Explanation:

Flexural rigidity is defined as the force couple  required to bend a fixed non rigid structure in one unit of curvature.

B(x)= EI

where E = young's modulus and

            I = moment of inertia of the beam
