About this tool
Reactions, maximum shear and moment for four load cases, with deflection when E and I are supplied.
SS+UDL wL/2, wL²/8, 5wL⁴/384EI; SS+P PL/4, PL³/48EI; cantilever wL²/2, wL⁴/8EI, PL, PL³/3EI.
Formula: M_max = wL²/8 δ = 5wL⁴/384EI
Example: Load case = Simply supported + UDL, Span / cantilever length (m) = 6, UDL (kN/m) = 20 → Max moment (kN·m) = 90, Max shear (kN) = 60.
Prismatic, small deflection. Not a code check; no load combinations, buckling or fire cases.
