a. Given the following materials and properties, arrange the materials from most suitable (place at the top of the list) to least suitable (place at the bottom of the list) in terms of the strength performance index. Hint: Remember to convert listed strengths to shear strengths b. Given the following materials, properties, and relative cost data, arrange the materials from most cost effective (place at the top of the list) to least cost effective (place at the bottom of the list) through a cost analysis. Hint: Remember to convert listed strengths to shear strengths. Yield Strength Material Aluminum alloy 7075 (heat treated) Carbon-fiber epoxy composite (Vf = 0.6) Steel alloy 4340 (annealed) Poly(methyl methacrylate)- PMMA (processed filament form Polyetheretherketone - PEEK (process filament form Silicon-nitride (hot-pressed) Alloy Ti-6Al-4V (solution heat-treated and aged) Density (g/cm³) 2.8 1.6 7.85 1.19 1.31 3.3 4.43 505 1 520 (tensile strength) 472 53.8 100 1000 1103 Relative Cost 4.6 100 2 3.8 255 400 35.3
