Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Linear elastic pure bending about the specified centroidal axis. Not an allowable-stress check.
Example Calculation
- Bending moment: 1000 N·m
- Extreme-fiber distance: 50 mm
- Second moment of area: 1000000 mm⁴
Bending moment = 1000 N·m; Extreme-fiber distance = 50 mm; Second moment of area = 1000000 mm⁴. Primary result: 50.
Frequently asked questions
How do I use this calculator?
Enter bending moment, extreme-fiber distance, second moment of area. The result updates automatically. Use Reset to restore the example values.
What method does it use?
stress=M ×1000 ×y/I.. Linear elastic pure bending about the specified centroidal axis. Not an allowable-stress check.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
