Solid Round Beams Deflection Calculation

This Mechanical Engineering Calculator is to compute the defection of simple solid round beams. It assumes the beam is supported on one end and the force is applied to the other end. Enter the length and diameter then select the material from the drop down menu. Click Result and read the beam deflection value in the output panel.

  • Length (Inches)

  • Diameter (Inches)

  • Force (Pounds)

  • Material

  • Deflection (Inches)

  • Bending Stress (PSI)


MI for Solid Round = (PI * Diameter4) / 64
Deflection = (Length3 * Force) / (3 * E * MI)
Bending Stress = (Force * Length) / (MI / (0.5 * Height))

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