Inputs
Simply supported beam, single central point load.
Tip: steel E ≈ 200 GPa. Scientific notation like 8.33e-6 is supported.
Results
- Support reaction (each)
- 500.0 N
- Max bending moment (center)
- 500.0 N·m
- Max bending stress
- 6.00 MPa
- Max deflection (center)
- 0.100 mm
Formulas
- M_max = P·L / 4
- σ = M_max / S
- δ = P·L³ / (48·E·I)
