🔷 FAQ

Q1: What is the section modulus used for?

A: Section modulus measures a bar’s resistance to bending. It’s essential in structural and mechanical design.

Q2: Is this calculator suitable for hollow or I-beams?

A: No, this calculator is only for solid rectangular bars. Use dedicated tools for hollow or I-shaped profiles.

Q3: Can I use inches as input units?

A: Yes. Simply select “inches” before calculating to get results in in³.

Q4: Can this be used for bending setup?

A: Yes, it’s useful for estimating material behavior under bending loads, especially in profile bending operations.
