Load/Stress Calculator
Simple beam or column stress check. Units: kN, m, mm, MPa.
Formulas (simply supported): Point at mid-span → M = W·L/4; UDL → M = w·L²/8. Units: W (kN), w (kN/m), L (m), sizes (mm). Stress in MPa.
Simple axial stress only (no buckling). Units: P (kN), sizes (mm), stress (MPa).
