3) An iron ore mine that ships its product via a railroad in northern Minnesota is going to increase production next month. The manager of this railroad is scrambling to find additional railcars to move this new traffic and contacts you at the Triple Eye Route to see what railcars you might have available for a short term lease until new cars arrive from the railcar manufacturer. The only railcars you have available are coal gondolas with a gross railcar load of 286,000 pounds, a tare weight of 52,000 pounds and a cubic capacity of 4,680 ft. a) For what density of coal have the gondolas been designed? b) If the body of the coal gondola can be represented by an open-top box with a height of 10 feet and a width of ten feet, how long is the body of the coal gondola? c) If the trucks, couplers, draft gear and other essential safety appliances for each coal gond ola weigh 35,000 pounds, and the cars are made of steel (density 500 lb/ft), what is the average thickness of the ends, sides and floor of the coal gondola body? d) If iron ore has a density of 150 lb/ft, what percentage of the cubic capacity of the coal gondola is filled with lading when it is loaded with iron ore? e) If the length of trains on the railroad in Minnesota is limited to 5,000 feet (excluding locomotives), how many tons of iron ore can each train move if it is loaded in the coal gondolas? Assume that the overall coupled length of each coal gondola is the length of the body plus five feet. 1) If a new gondola were designed specifically for iron ore service using the same height, width, steel thickness and running gear weight as the coal gondola, how much shorter would it be compared to the coal gondola? g) What would be the tare weight of the new iron ore gondola described in part f? h) Given the same constraints described in part e, how much iron ore can one train move if the new iron ore gondolas are used? 3) An iron ore mine that ships its product via a railroad in northern Minnesota is going to increase production next month.
