A brittle mаteriаl hаs an ultimate strength оf 460 MPa. A member made оf this material is subjected tо its design loads. At the critical point in the member, the nonzero stress components are as follows. Determine the factor of safety used in the design based on the maximum principal strain criterion. Assume ν = 0.22.σxx = 50 MPaσyy = 60 MPaσxy = 60 MPa
