The tool is fully functional, so visit our Free Calculator to get started! It will work for all simply supported, determinant beams and is capable of taking point loads, concentrated moments and distributed loads. It is also extremely adjustable and customizable to allow you to generate your own beams. It is an extremely accurate tool, and unlike current calculators, very user-friendly. It is an extremely useful tool for university, college and high school students who tediously have to redraw BMDs and SFDs for assignments and practice/tutorial questions.

We also have a Tutorial page that will help university students with calculations expected in their engineering degree as well as high school students. These students can learn how to calculate and generate Shear Force and Bending Moment Diagrams and we understand the process of beam analysis can sometimes be difficult, so we have provided a simple step by step guide of how to calculate bending moment and shear force diagrams. Included are simple bending moment equations and formulas which well help with your calculations. There are also examples and random beam generators which will allow you to experiment on how different loads affect beam analysis and the shear force and bending moment of a beam.

Sick of studying for your engineering university degree? Forget all about Shear Force and Bending Moment Diagrams for Beams and try playing engineering and physics games on our Take a Break page.

Although the diagrams are accurate to 3 decimal places, we still do not recommend that this calculator is used as a sole tool for actual simple beam design. The calculator is intended for educational use only and can be a great tool for checking answers and experimenting on how different loads and reactions affect beam design.

We appreciate your support and feedback, so if you have any questions or concerns please let us know on our Feedback pages.

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 calculations are only set to draw the shear force and bending moment of a beam at the moment. The calculator cannot calculate bending moment and shear forces in frames at this stage.
