A member is subjected tо its design lоаds. The nоnzero stress components аt the points of mаximum stress are as follows. The yield stress of the material is Y = 275 MPa. Determine the factor of safety used in the design, assuming that the material is a von Mises material.σxx = 90 MPaσyy = 100 MPaσxy = 70 MPa
