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 that at an average speed of 5 mph, that 200ft is required both to accelerate and decelerate. The operating efficiency to a 50-min hour. It will take 0.80 min to load this scraper.
