What reading level is A Practical Treatise On Street Or Horsepower Railways Their Location Construct book?
To quickly assess the difficulty of the text, read a short excerpt:
10 h.
Maximum velocity unloaded, in miles 14. 7 miles. 10. 4m. 8. 5m. 7. 3 in. G. G m. Cm. 5. 5m. 5. 2m. 4. 6m.
per hour, This he considers may be taken as very nearly the law of decrease of speed by increased duration of labor when a horse moves on a level road, unloaded. If the road be inclined, the velocity of ascent will decrease in proportion to the rise of the inclination, and proportion ally increase in the descent.
From calculation it would appear that a horse can haul seven times a gre...ater weight on a level road than he can on an inclination of 5 in 100, and prac tical experience proves that on a line of five miles where there are continually undulating grades, varying from level to 5 in 100, two horses can regularly haul four tons in one hour. This then would tend to clearly demonstrate that the system now adopted on level streets of attaching two horses to a car, whose weight when loaded will perhaps not exceed four tons, the capacity of the horses being twenty-eight tons, is a waste of motive pow r er, arising either from a miscalculation of the horses power, inferiority of stock, or defectiveness in the wheels or track.
