A free, online beam calculator to generate shear force diagrams, bending moment diagrams, deflection curves and slope curves for simply supported and cantilvered beams. One of these methods is the separation into a small deflection plate and a thin membrane described by a simple third order polynomial expression. The moment of inertia values we obtained tell us that the beam is harder to bend with a vertical load and easier to bend if subjected to a horizontal lateral load. This calculator is based on Euler-Bernoulli beam theory. Now that we know the concepts of modulus of elasticity and moment of inertia, we can now understand why these variables are the denominators in our beam deflection formulas.

Beam Deflection and Stress Formula and Calculators This is because excessive deflection can result in unwanted aesthetic effects, such as sagging floors, cracking of finishes, or discomfort for the users. This difference in the moment of inertia values is the reason why we see beams in this configuration wherein their height is greater than their width. The plate is flat, of uniform thickness, and of homogeneous isotropic material; the thickness is not more than about one quarterof the least transverse dimension, and the maximum deflection, all forces, loads and reactions are normal to the plane of the plate; and, the plate is nowhere stressed beyond the elastic limit. Now that we know these values, let us consider the load this bench will carry.
