This calculator calculates the deflection, bending stress using length (inches), diameter (inches), wall thickness(inches), force (pounds), material values.
Formula:
MI for Solid Round Beams = (pi * (OD4 - ID4)) / 64
Deflection = (length3 * force) / (3 * E * MI)
Bending Stress = (force * length) / (MI / (0.5 * height))
MI = Moment of Inertia
E = Modulus of Elasticity in psi
