This calculator can solve basic truss systems giving the internal forces and stresses in each beam. Just as a fun fact, there is no limit to the number of beams you can enter. Let's see who can break it first but good luck doing the hand calculations to prove its wrong!

This calculator calculates the stresses in each lamina of a laminate given the laminate ordering and the material properties. This is not limited to symmetric and balanced laminates. You can also change the angles of the lamina in the layer build setup to see real time effects.
