The calculations are only set to draw the shear force and bending moment of a beam at the moment. In this article, we will discuss Bending moment Definition diagram and calculation. The bending moment at any location along the beam can then be used to calculate the bending stress over the beam's cross section at that location.

Besides calculating the bending moment of a beam, it is also intended to draw axial force, shear force, bending moment, and beam deformation diagrams. Bending moment is a torque applied to each side of the beam if it was cut in two - anywhere along its length. It can also be visualized as torque as it is also force multiplied by the distance from point of its application. First and the most important thing for BM is its sign convention.

The hinge applies a clockwise (+) moment (torque) to the RHS, and a counter-clockwise (-) moment to the LHS. Example Bending-Moment Page 1 . The calculator can accommodate up to 2 point loads, 2 distributed loads and 2 moments on a single beam, which will allow you to enter any number of combinations of loads that you may be asked in a single beam analysis question.
The bending moment, M, along the length of the beam can be determined from the moment diagram. Simply model your beam using the calculator, and hit solve. For example consider the following figure which shows the free body diagram of a simply supported beam having F 1 , F 2 , F 3 and F 4 as the applied loads on the beam and R A , R B as the support reactions. Under our paid version the calculator will even show you the full hand calculations, showing the steps taken to hand calculate your bending moment diagrams. In its free version, you can draw a free body diagram of a beam with a maximum of 10 nodes. It will show you the step by step calculations of how to draw a bending moment … These instructions will help you to calculate and draw shear and bending moment diagram, as well as draw the resulting deflection.

Bending moment at a section of beam is defined as the algebraic sum of the moment of all the forces acting on one side of the section. Bending Stresses in Beams. EngiLab is a featured bending moment calculator for Windows. The bending moment (BM) is the algebraic sum of the moments of the forces and reactions acting on one side of the section about the section.
