Mohr's circle is a graphical technique that permits transformation of stress from one plane to another and can also lead to the determination of the maximum normal and shear stresses. This file simply draws Mohr's circle with the correct stress elements while labeling the principle stresses and maximum shear stresses. Simple extensions to finding the rotation angle for maximum normal and shear stresses are easily done from this as well.
