Stress between load and "a" load point

Stress between load and "a" load point

Stress between load and "b" load point

Stress between load and "b" load point


Stress at load application

Stress at load application

If the cross section is constant this is the maximum stress.


Deflection for location between load and "a" point

Deflection between load and "a" point

Deflection for location between load and "b" point

Deflection between load and "b" point


Maximum deflection at load

Maximum deflection at load

Let be the length of the shorter segment and b of the longer one.
The maximum deflection

Beam  Deflection is in the longer segment, at

Beam Deflection


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