Section modulus - Wikipedia

Section modulus is a geometric property for a given cross-section used in the design of beams or flexural meers. Other geometric properties used in design include area for tension and shear, radius of gyration for compression, and moment of inertia and polar moment of inertia for stiffness. Any relationship between these properties
