You point out that railroad tracks divide the field into parallel sectors, like the lines on a football field, so that each stack of metal is no more than 15 feet from a track. each stack contains 390 pieces of metal. each piece weighs 92 pounds and is about a yard long and just over 4 inches high and 4 inches wide. you tell the students that, working as a team, they are to pick up each piece, walk up a ramp to a railroad car that will be positioned next to each stack, and then neatly position and stack the metal for shipment. that’s right, you repeat, 92pounds, walkup the ramp, and carrythe metal onto the rail car. anticipating their questions, you explain that a forklift could be used only if the metal were stored on wooden pallets (it isn’t); if the pallets could withstand the weight of the metal (they would be crushed); and if you, as their supervisor, had forklifts and people trained to run them (you don’t). in other words, the only way to get the metal into the rail cars is for the students to carry it. based on an old report from the last time the company sold some of the metal, you know that workers typically loaded about 30 pieces of metal parts per hour over an 8-hour shift. at that pace, though, it will take your six students 6 weeksto load all of the metal. but the purchasing manager who sold it says it must be shipped in 2weeks. without more workers (there’s a hiring freeze) and without forklifts, all of the metal has to be loaded by hand by these six workers in 2 weeks. but how do you do that? what would motivate the students to work much, much harder than they have all summer?
