A rigging job calls for lifting a structure that weighs 150 tons. Two cranes are available, one with a rated capacity of 85 tons and the other with a rated capacity of 120 tons. The total weight of the rigging required to make the lift is 15 tons, of which 10 tons is to be carried by the larger craneand 5 tons is to be carried by the smaller crane. If the cranes are to be loaded in proportion to their net capacities, what should be the approximate net load on the 120-ton crane?

Two materials, A and B, are to be separated using two unit operations, 1 and 2. The feed has 10 tons/h A and 4 tons/h B. The split (fraction of material rejected by each operation) is given in Table P5-14. a. Which sequence of operations, (l?2) or (2?1), will yield the greatest recovery of material A? b. What will be the purity of material A using that sequence? c. What will be the efficiency of separation for the entire process train with regard to material A using the Worrell-Stesed equation?
The cost of transportation of materials has to be allowed for in the estimate, but this item is not usually measured or even referenced in the takeoff. List six other similar items.
Calculate the cost per cubic yard to place concrete using each of the alternatives described. The work in both cases consists of placing 140 cubic yards of concrete in footings. a. Using a crane and bucket at a price of $225 per hour, including an operator, with a crew consisting of 6 laborers, a cement finisher, and a foreman. The concrete will be placed in 7 hours using this setup, and transportation of the crane costs $390. b. Using a concrete pump at a price of $295 per hour, including an operator and a crew consisting of 5 laborers, a cement finisher, and a foreman. With this setup, concrete is placed in 6 hours and transportation of the pump costs $290.
