Torsion calculator finds torsional stiffness constant, shear stress and angle of
twist parameters of a solid rectangular cross section, which is under twisting moment. The calculator is only
valid for solid rectangular cross sections and bars. The formulas used for calculations are given in the "List of
Equations" section.
