Bending, Deflection and Stress Equations Calculator for
Fixed at Both Ends with Uniform Loading

Beam Deflection and Stress Formula and Calculators

Structural Beam Deflection, Stress, Bending Equations and calculator for a Beam Fixed at Both Ends with Uniform Loading.

Calculator - Coming soon


General Stress at any Given Point


Stress at Critical Locations/Points

Maximum Stress (at fixed ends)

Stress is zero at:
x = 0.7887l
and
x = 0.2113l

The greatest negative stress (at center)


Deflection at any Point


Critical Deflections

Maximum Deflection (Center of Beam)


Where:

E = Modulus of Elasticity psi

(N/m2)

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)
u = Some distance as indicated inches (m)
a, b = Some distance as indicated inches (m)
L = 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.
