Beams come in various sizes and shapes.They are usually,either homogeneous or composite.A homogeneous beam is one that is mode of one material,such as,wood or steel.A composite is one made of materials that are not the same,such as,a concrete beam with steel reinforcing.Some BeamBeam Calculator - Solid Round BeamsDeflection = (Length3 * Force) / (3 * E * MI) Bending Stress = (Force * Length) / (MI / (0.5 * Height)) Where,MI = Moment of Inertia.E = Modulas of Elasticity in psi.It assumes the beam is supported on one end and the force is applied to the other end.Example Length (Inches) = 15.Diameter (Inches) = 5.Beam Deflection Calculator·Calculating beam deflection requires knowing the stiffness of the beam and the amount of force or load that would influence the bending of the beam.We can define the stiffness of the beam by multiplying the beam's modulus of elasticity,E,by its moment of inertia,I.The modulus of elasticity depends on the beam's material.
