Three materials are being considered for a design. The material design requirements specify that the part must support a load of 140,000 Ib in simple tension and that the part have a maximum extension limit of 0.035 in. over the length of 10 in. The data for the materials being considered is:

a.       What is the minimum material cost for each of the materials that meets the design requirements?

b.      What is the weight of material used to meet the design requirements at minimum cost?

c.       What is the volume of the material used to meet the design requirements at minimum cost?

d.      How much must the unit cost of material A be reduced to make it the lowest-cost material meeting the design requirements?
