SUMMARY
The maximum shear stress in a 3D stress state is calculated using the formula: max shear stress = (max principal stress - min principal stress)/2. This equation is applicable for determining shear stress in three-dimensional scenarios. The discussion also highlights the importance of distinguishing between normal stress and principal stress when calculating shear stress on an arbitrary plane. Understanding these concepts is crucial for accurate stress analysis in engineering applications.
