Section Modulus in Load Factor Design (LFD) Formulas

Section Modulus is a geometric property for a given cross-section used in the design of beams or flexural members. And is denoted by S. Section Modulus is usually measured using the Cubic Millimeter for Volume. Note that the value of Section Modulus is always positive.

FAQ

What is the Section Modulus?

Section Modulus is a geometric property for a given cross-section used in the design of beams or flexural members. Section Modulus is usually measured using the Cubic Millimeter for Volume. Note that the value of Section Modulus is always positive.

Can the Section Modulus be negative?

No, the Section Modulus, measured in Volume cannot be negative.

What unit is used to measure Section Modulus?

Section Modulus is usually measured using the Cubic Millimeter[mm³] for Volume. Cubic Meter[mm³], Cubic Centimeter[mm³], Liter[mm³] are the few other units in which Section Modulus can be measured.
