Calculadora de Momento Fletor — Formula
## Bending Moment
**Uniform load: M = wL squared / 8**
**Center point load: M = PL / 4**
Both produce maximum moment at mid-span for a simply supported beam. If both loads are present, add the moments together (superposition).
**Uniform load: M = wL squared / 8**
**Center point load: M = PL / 4**
Both produce maximum moment at mid-span for a simply supported beam. If both loads are present, add the moments together (superposition).
Exemplo Resolvido
14 ft beam with 250 lb/ft uniform load.
- M = 250 x 14 squared / 8 = 250 x 196 / 8 = 6,125 ft-lbs
- No point load contribution
- Required section modulus = M / Fb (allowable bending stress)
