A structural member 250 mm (10 in.) long must be able to support a load of 44,400 N (10,000 lbf) without experiencing any plastic deformation. Given the following data for brass, steel, aluminum, and titanium, rank them from least to greatest weight in accordance with these criteria. Then rank the materials from least expensive to most expensive.
Alloy Yield Strength [MPa (ksi)] Density (g/cm3) Cost ($US/kg)
Brass 345(50) 8.5 10.90
Steel 690(100) 7.9 3.60
Aluminum 275(40) 2.7 8.50
Titanium 480(70) 4.5 100.00
