Summary: Because of the amount of handling that occurs during material production, within warehouses, and during manufacturing operations, along with the handling of loading, unloading, and shipping, material mix-ups and mixed materials are not an uncommon occurence. Mixed materials also occur when industrial scrap is collected, or when discarded products are used a new raw material through recycling. A case of mixed materials has been identified, and you have been called upon to devise a means of separation. Assume that you have the equipment to perform each of the tests described in our discussion. For each of the material combinations below, determine a procedure that could accomplish such a separation. Use standard data-source references to help you identify distinguished properties. hot-rolled bars of AISI 1020 and 1040 steel stainless steel sheets of Type 430 ferritic stainless and Type 316 austenitic stainless. 6061-T6 aluminum and AZ91 magnesium that have become mixed in a…

3. An aircraft manufacturer uses 1,000,000 special rivets per year at a uniform rate. The rivets are made on a single-spindle automatic screw machine at the rate of 3,000 per hour. The manufacturing cost is $0.0052 per rivet and the storage cost is estimated to be $0.0008 per rivet per year. The set-up cost is $40 per set-up. Calculate the economic production quantity and the allow- able variation in this quantity for a maximum deviation from the minimum cost of 5%. Assume the machine operates 1,700 hours per year,

A firm is trying to decide which of two weighing scales it should install to check a package-filling operation in the plant. The ideal scale would allow better control of the filling operation, hence less overfilling. If both scales have lives equal to the 6-year analysis period, which one should be selected? Assume an 8% interest rate.

A contractor needs 3715 m³ of aggregate base for a highway construction project. It will be compacted to a dry unit weight of 18.9 kN/m³. This material is available in a stockpile at a local material supply yard at a water content of 7.75%, but is sold by the metric ton and not by cubic meters (ton 3 1000kg). a. How many tons of aggregate should the contractor purchase? Round your answer to the nearest whole number. b. A few weeks later, an intense rainstorm increased the water content of the stockpile to 14%. If the contractor orders the same quantity for an identical section of the highway, how many cubic meters. of compacted aggregate base will he produce?
