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)
x = Some distance as indicated inches (m)
= 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.
