Calculator Introduction
Given the stress components sx, sy, and txy, this calculator computes the principal stresses s1, s2, the principal angle qp, the maximum shear stress tmax and its angle qs. It also draws an approximate Mohr's cirlce for the given stress state.

Inputs
  Normal Stress sx:    
  Normal Stress sy:    
  Shear Stress txy:    
Answers
  Maximum Normal Stress s1:  1.65  MPa
  Minimum Normal Stress s2:  -0.547  MPa
  Principal Angle qp:  32.9  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.
