Section modulus is a geometric property of a cross-section that measures its resistance to bending and flexural stress. It is defined as the ratio of the moment of inertia of the section about a given axis to the distance from that axis to the outermost fiber of the section. Understanding section modulus is crucial in evaluating how well a structural element can resist bending under load, making it particularly relevant in the context of repair and strengthening techniques.
congrats on reading the definition of Section Modulus. now let's actually learn it.
