Question

2. A machine component experiences critical static stresses of T,-15 kpsi Oz#10 kpsi, ơ,--50 kpsi, Determine between ASTM grade 25 cast iron (Su 26 kpsi, Sac 9 kps) and ASI 1030 HR stecl (S. 470 MPa, S, 260 MPa) which would be a beter ehoice for the stress state, on the failure model that is least conservative.
