Inputs
You don't need to fill all fields—just enter the stresses on the XY plane (\(\sigma_x\), \(\sigma_y\), \(\tau_{xy}\)) or in arbitrary directions (\(\sigma\prime\),\(\tau\prime\)) based on what's given in your problem. Once enough inputs are given, the the solve button will be active.

Solution
To start solution, number of unknows should be equal to number of equations. Please note that the results are approximations based on numerical methods, not exact solution and in some cases, a solution may not be found.
