How to Draw Mohr’s Circle

Mohr’s Circle is used to graphically determine the principal normal and shear stresses. First, some definitions: Tensile stresses are positive. Compressive stresses are negative. Clockwise shear stresses are positive. Counterclockwise shear stresses are negative. To draw Mohr’s circle, and find the principal normal and shear stresses, you must know the stresses applied to the object, […]
