This is a resistance calculation problem for construction equipment. Given facts shown below, answer the four questions: Facts: • A fully loaded wheeled scraper (empty weight = 60.0 tons; fully loaded weight = 90.0 tons) must travel up a 3% stope 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 .
Type all your work in detail with a final answer under each question below. Q1) What is the total resistance force in lb. that the machine is going uphill? 1 Q2) Determine the effective grade (%) for the total resistance of going uphill? Q3) What is the total resistance force in lb. that the machine is coming downhill (with an empty weight)? Q4) Determine the effective grade (%) for the total resistance of coming downhill (with an empty. weight)?
