Based on the governing equation for the theory of pure bending which of the following is valid

Bending moment = the product of bending stress and the section modulus Bending strength = product of modulus of elasticity and curvature Moment resistance = the product of flexural rigidity and the curvature Bending moment = flexural rigidity per unit radius

Explanation:

The bending equation states that:

$\frac{σ}{y} = \frac{M}{I} = \frac{E}{R}$

Various terms in the above bending equation are:

σ = Bending stress, y = Distance from the neutral axis, M = Bending moment, I = Area moment of inertia, E = Modulus of elasticity, R = Radius of curvature

From the above equation,

$M = \frac{σ \times I}{y}$

M = σ × Z (Where, Z = Section modulus = I/Y)

Bending moment = the product of bending stress and the section modulus
