Where:

E = Modulus of Elasticity psi

(N/mm2)

I = Moment of Inertia in4 (mm4)
W = Load, Total lbf (N)
w = Unit Load lbs/in (N/mm)
y = Beam Deflection inches (mm)
a, b, c, d, x, L = Some distance as indicated inches (mm)
n = Distance neutral axis inches (mm)
Vmax = Shear Load lbf (N)
Mmax = Beam Moment lbs-in (N-mm)
θmax = Slope Angle degree (radian)
σmax = Beam Stress max. psi (N/mm2)
  • Deflections apply only to constant cross sections along entire length.
