You decided to use a loader and 15-cubic-yard dump trucks (manufacturer's performance data is shown in the Table 1) to haul the material from the borrow to the construction sites. The trucks are powered with 185-horsepower, four cycle naturally respirated engines, and the gear train efficiency is estimated to be 0.8. The road has an average uphill grade of 2.5% when travelling from the borrow site to the construction site. The project site is at the elevation of 2,000 feet. The gross weight of the fully loaded truck is 35 tons and 60% of the loaded weight is carried by the rear driving wheels. Tire penetration is estimated to be 1.5 inches and the coefficient of traction is estimated to be 0.6. The trucks are not equipped with radial tires. a. What is the maximum speed of a fully loaded truck traveling from the borrow site to the construction site? b.
