about 8 lbs. per ton of weight ona level track. For wagons on macadamized roads b = \ inch,but on soft ground from 2 to 3 inches. Secondly, when the roadway is perfectly elastic. This ischiefly of theoretic interest, since at first sight no force wouldbe considered necessary to maintain a uniform… … Fig. 189. occur. Fig. 189 gives an exaggerated view of the circum-stances, P being the horizontal force applied at the centrenecessary to maintain a uniform motion. The roadway (rub-ber for instance) is heaped up both in front and behind theroller, 0 being the point of greatest pressure and…
