At a point in a bar of cast iron, the principal stresses are 60 MPa tensile and 120 MPa compressive whereas the third principal stress is zero. Find the factorsof safety based on the elastic limit when the criterion of failure is principal stress theory. Assume the elasticlimit of cast iron is 90 MPa in tension and 440 MPa in compression
