Efficiently calculate the section modulus for rectangular hollow sections. This critical value helps engineers and designers assess a beam's bending strength and predict its resistance to applied loads, ensuring safe and optimal structural design. Use our tool for precise results.
Formula:
The section modulus (S) for a rectangular tube is calculated using the formula:
S = (B × H3 - b × h3) / (6 × H)
- B = Outer Width of the rectangular tube
- H = Outer Height of the rectangular tube
- t = Wall Thickness of the rectangular tube (assumed uniform)
- b = Inner Width of the rectangular tube (calculated as B - 2 × t)
- h = Inner Height of the rectangular tube (calculated as H - 2 × t)
This formula is derived from the moment of inertia (I) and the distance from the neutral axis to the extreme fiber (y = H/2).
