A loaded railroad car has a weight of 35 tons and is supported by eight 32-in.-diameter wheels

Question:

A loaded railroad car has a weight of 35 tons and is supported by eight 32-in.-diameter wheels with 5-in.-diameter axles. Knowing that the coefficients of friction are μs = 0.020 and μk = 0.015, determine the horizontal force required

(a) For impending motion of the car,

(b) To keep the car moving at a constant speed. Neglect rolling resistance between the wheels and the track.
