Question:

An element in pure shear is subjected to stresses Txy = - 14.5 MPa, as shown in the figure. Using Mohr's circle, determine:
(a) The stresses acting on an element oriented at a counterclockwise angle ( = 22.5° from the x axis
(b) The principal stresses. Show all results on sketches of properly oriented elements.
