Question

Use the coordinates of point x and the center C of the circle to determine the acute central angle. The other central angle is 180° minus the acute angle. For this Mohr’s circle, determine the magnitude of the central angle between: (a) point x and the point representing the principal stress σp1. (b) point x and the point representing the principal stress σp2.

Answer 1

, intermediate, and minimum intensity.If we assume that the principal orientation of the element and the principal stresses are known, this condition is known as “triaxial stress”.If we view each face of this element in 2

(the
