Beam Deflection
Formula: deflection = PL³ ÷ 48EI (centre-point load, simply supported)
Inputs

Maximum Deflection
0.006349 m
Warnings & checks
- ⚠Warn if deflection exceeds L/360 (serviceability limit)
Recommended next actions
- →Use a deeper section to reduce deflection (I scales with depth^3)
- →Check shear and bending stress separately
Use for estimation. Verify safety-critical calculations with qualified review.
