Flexural Rigidity

Flexural rigidity refers to a material or structure's ability to resist bending when a force is applied. It depends on two factors: the material's stiffness (modulus of elasticity) and the shape or size of the structure (moment of inertia). A higher flexural rigidity means the structure is less likely to bend or deform under load. For example, a thick, sturdy beam has greater flexural rigidity than a thin, flexible one, enabling it to support heavier weights without bending significantly. This property is crucial in engineering to design safe, stable structures like bridges, floors, and beams.
