Answer: D - modulus of elasticity and area moment of inertia
Flexural rigidity of beam is a product of modulus of elasticity and area moment of inertia.
From the bending moment equation,
σ/y = M/I = E/R
Flexural rigidity = EI
Unit of flexural rigidity: Nm2
- E= modulus of elasticity
- I = area moment of inertia
- The bending moment required to produce unit curvature in a beam is given by flexural rigidity.
- Flexural rigidity describes the resistance provided by a structure when bent.
- The beam with a higher flexural rigidity has a lower deflection value.
