Find the volume and weight of limestone rocks you will need for your project using this easy-to-use limestone calculator. Calculates stresses and deflections in straight beams Builds shear and moment diagrams Can specify any configuration of constraints, concentrated forces, and distributed forces References The quick answer is anything! However, these formulas can only solve simple loads and a combination of these loads. 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. Downward loads tend to deflect the beam downwards. Beam deflection is the vertical displacement of a point along the centroid of a beam.
