The state of stress at a point is given by the stress components sx = 70 MPa, sy = 10
MPa and ?xy = - 40 MPa. Using Mohr''s circle, find (i) Principal stresses, and (ii) Principal
planes. Also, determine the normal and shear stress components on planes making
25°, 40° and 60° respectively with the x plane.
