Determine the total force needed to overcome axle friction

Reference no: EM13319322

A 100-ton train traveling on a horizontal track requires 400 hp to maintain a constant speed of 50 mi/h. Determine (a) the total force needed to overcome axle friction, rolling resistance, and air resistance, (b) the additional horsepower required if the train is to maintain the same speed going up a 1-percent grade.
