Stripping overburden in the Illinois coal belt, the Dusty Coal Company uses 270-HP Track-type tractors and drawn scrapers. The overburden is a very soft loam that weighs 2800 lb/yd (loose). Estimated rolling resistance factor the haul road is 3000 lb/ton. If the scraper weighs 35,000 lb (empty) and carries 25 loose cubic yards per trip. What is the rolling resistance of the loaded unit?
