Abstract

(1) IN this work Mr. Wimperis has made available in an expanded form the substance of a series of lectures delivered in 1913 at the Finsbury Technical College on the application of power to road transport. In the chapter devoted to the measurement of power, the author describes fully the principles of construction, and the method of using the ingenious accelerometer, which he invented in 1909; by means of this instrument many measurements have now been made of the tractive effort exerted in moving motor-cars and wagons at various speeds, both on the level and on grades, and thus valuable experimental data have been accumulated as a basis for the design of motor vehicles. In a later chapter Mr. Wimperis shows by actual examples how the data obtained by such an instrument and from bench tests of engines may be utilised to design a motor vehicle from prescribed conditions; both motor wagons and touring cars are dealt with, and this chapter should prove of great assistance to designers of motor-cars.
