Beam Deflection of Hollow Rectangular Formula - Mechanical Engineering

Formula:

Hollow Rectangular Beams Deflection

Inside_width = Width - (2 * Wall Thickness)
Inside_height = Height - (2 * Wall Thickness)
MI for hollow rectangle beams = ((Width * Height3) - (Inside_width * Inside_height3)) / 12
Deflection = ((Length3 * Force / (3 * Material * MI)) * 0.0393701
Bending Stress = (Force * Length) / (MI / (0.5 * Height))



Where,

MI = Moment of Inertia
E = Modules of Elasticity in psi
