Facts: • A fully loaded wheeled scraper (empty weight = 50.0 tons; fully loaded weight = 85.0 tons) must travel up a 3% slope on a muddy haul road. • The average tire penetration of machine is estimated to be 5.5 inches. After dumping the loaded weight, the scraper returns downhill with an empty weight.
