What reading level is The Electric Railway in Theory And Practice book?
To quickly assess the difficulty of the text, read a short excerpt:
With regard to the possible average effi- ciency of street car motors, it is quite within bounds to say that with a properly designed single motor 80 per cent, is quite attainable ; and even this efficiency may be somewhat raised, though it is hardly likely to reach 90 per cent. , on account of the present necessity for regulating devices of some kind or other and the need for a comparatively light *The Electrical World, May 31, 1890.
THE EFFICIENCY OF ELECTRIC TRACTION. 221 weight machine. In ...most street car systems, even to-day, the armature speed is somewhere nearly i. Ooo revolutions per minute, at usual car speeds; and consequently there must be a reduction, by gearing, to one-tenth or one-twelfth the armature speed, between the armature and the car axle. This has been until recently generally accomplished by a double set of spur gears. The efficiency of such gearing is usually given in books on engineering at over 90 per cent. For each set of gears, and with reasonable precautions against Cirt this figure may be reached readily enough.
