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 Tresca material.σxx = 60 MPaσyy = 60 MPaσxy = 50 MPa
