1. You wish to design the rung on a ladder. The ladder should be light in weight so that it can be easily transported and used. The rungs on the ladder should be 0.25 in. x 1 in. and are 12-in. long. Design a material and its processing for the rungs.
2. We have determined that we need an alloy having a density of 2.3 ± 0.05 g/cm3 that must be strong, yet still have some ductility. Design a material and its processing that might meet these requirements.
