It also draws an approximate Mohr's cirlce for the given stress state. Inputs  Normal Stress sx: Pa kPa MPa GPa psi ksi Normal Stress sy: Shear Stress txy:    Maximum Normal Stress s1: 1.65  MPa Pa kPa MPa GPa psi ksi Minimum Normal Stress s2: -0.547  MPa Principal Angle qp: 32.9  deg rad deg Maximum Shear Stress tmax: 1.10  MPa Maximum Shear Angle qs1: 77.9  deg and qs2: -12.1  deg  The Mohr's circle associated with the above stress state is similar to the following figure. However, the exact loaction of the center sAvg, the radius of the Mohr's circle R, and the principal angle qp may be different from what are shown in the figure. Equations behind the Calculator The formulas used in this calculator are,     Further information can be found in the plane stress, Mohr's Circle, and the Mohr's Circle usage pages.
