What is Moment of Resistance

The algebraic sum of moments of the internal forces (compressive and tensile forces developed in the cross-section due to bending) about the neutral axis of the section is called the moment of resistance of the section. For equilibrium condition, the moment of resistance of a section will be equal to the applied bending moment at that section.

The moment of resistance of a section corresponding to the maximum permissible stresses in the material is called the limiting moment of resistance of the section. This indicates the maximum bending moment that could be resisted by the section without the stresses exceeding the permissible values.
