Beam Deflection and Stress Formula and Calculators

Structural Beam Deflection, Stress, Bending Equations and calculator for a Cantilevered Beam with One Load Applied at End.

Bending, Stress Cantilevered Beam One Load Applied at End Calculator

Stress at specific point

Stress at the support (must be constant cross section)

Deflection at specified point

Deflection at the unsupported end


E =  Modulus of Elasticity psi


I = Moment of Inertia in4 (m4)
W =  Load lbs (N)
s =  Stress at the cross-section being evaluated lbs/in2 (N/m2)
y = Deflection inches (m)
Some distance as indicated inches (m)
x = Some distance as indicated inches (m)
Z = section modulus of the cross-section of the beam    
Z = I distance from neutral axis to extreme fiber (edge)    
  • Please note letter "" (lower case "L") is different than "I" (Moment of Inertia).
  • Deflections apply only to constant cross sections along entire length.
