Deflection Solid Rectangular Beams Formula

Equation for calculate deflection solid rectangular beams is,

MI for Solid Rectangular Beam = ((Height³ x Width) / 12)
Deflection = (Length³ x Force) / (3 x E x MI)
Bending Stress = (Force x Length) / (MI / (0.5 x Height))

Where,
MI = Moment of Inertia
E = Modulus of Elasticity in psi
