materials? pan including weight of parts (aluminum weighs 0.098 Ib/in3; Bakelite 0.162 lb/in2), number of each part needed, part name, material, materi description and supplier, and unit cost. 19. Using Figure 2.15, develop a bill of materials for an 8-in aluminum fryino The cost per 1000 lb of aluminum is $1350.00. The cost per 1000 lb of Bakelite is $700.00. 20. Using the bill of materials developed for problem 19, calculate the yearly material cost for 200,000 of these frying pans. 21. Develop a planning sheet for manufacturing finished picture frames. The costs are: labor, $4.80 an hour; wood, $0.50 a foot; nails, $0.02 a piece and varnish, $1.30 a quart. Estimate equipment usage and cost. 22. A manufacturer of staplers has the choice of two processes to produce the housing of the staplers. Method I produces the part with a punch press and smooths it with an abrasive belt grinder. Method II produces the part by casting and smooths it with an abrasive belt grinder. The manufacturer expects to produce 10,000 units per month. The present interest rate is 12%. The factors on which the manufacturer will base the decision are shown in the accompanying table. Determine the monthly cost of each alternative. materials? pan including weight of parts (aluminum weighs 0.098 Ib/in3; Bakelite 0.162 lb/in2), number of each part needed, part name, material, materi description and supplier, and unit cost. 19.
