A wheel tractor-scraper is carrying a 50,000 lb load while operating on a level grade. Assume no power derating is required for equipment condition, altitude, and temperature. What minimum value of coefficient of traction between the tractor wheels and the traveling surface is needed to overcome an equivalent rolling resistance of 12%? For the fully loaded condition 40% of the weight is distributed to the drive axle. Operating weight of the scraper when empty is 70,000 lb.6.4 (5 pts) A wheel tractor-scraper is carrying a 50,000 lb load while operating on a level grade.
