Determine the cycle time for a single-engine scraper rated at 21 cy heaped that is used to haul material from a pit to a fill 900 ft away under severe conditions. The average haul speed will be 14 mph and the average return speed will be 20 mph. Assume, at an average speed of 5 mph, that 200 ft is required both to accelerate and decelerate. The operating efficiency will be equal to a 50-min hour. It will take 0.80 min to load this scraper.
