Unformatted text preview: σ 2/3 vs ρ P I chart (from the W Chapter of Callister) in your notes locate Ti, Al and steel. Pick Ti-6Al- 4V, 2024T351 and 4340 Oil quenched and tempered, and calculate the P I for each. (Recall g/cm 3 = Mg/m 3 for density.) (Ans: Ti about 24 MPa m 3 /Mg, Al about 17 MPa m 3 /Mg,and 4340 about 17 MPa m 3 /Mg). Note where they sit on the materials chart. C . Using Appendix C in Callister, rank the three choices from B using the P I for strength against relative cost σ 2/3 /CR ρ . Use midrange values for CR if necessary. (Ans: Ti about .24 MPa m 3 $ / $ Mg, Al about 1.5 MPa m 3 $ / $Mg,and 4340 about 6 MPa m 3 $ / $ Mg.)...
