Question
Q)From the properties database presented in Appendix B (of Introduction and Fundamentals), select the metal alloys with stiffness performance indices greater than 26.0 (for E and r in units of GPa and g/cm3 , respectively).
Q)Also, using the cost database [Appendix C (of Introduction and Fundamentals)], conduct a cost analysis in the same manner as the case study. Relative to this analysis and that in part (b), which alloy would you select on a stiffness-per-mass basis?
Q)Now select the metal alloys with strength performance indices greater than 120 (for sy and r in units of MPa and g/cm3 , respectively), and rank them from highest to lowest P.
Q)Using the cost database, rank the materials in part (d) from least to most costly. Relative to this analysis and that in part (d), which alloy would you select on a strength-per-mass basis?
Q) Which material would you select if both stiffness and strength are to be considered relative to this application? Justify your choice.
