The design lоаds оf а member mаde оf a brittle material produce the following nonzero stress components at a critical section in the member. The ultimate strength of the material is 370 MPa. Determine the factor of safety used in the design based on the maximum principal stress criterion.σxx = –60 MPaσyy = 110 MPaσxy = 120 MPa
