To quickly assess the difficulty of the text, read a short excerpt:
The two lifts for each side were made as near the same time as possible, in order to obtain the action of the two motors, running under like conditions. Tbe curves for each leaf, in order to prove that the motors take the same power, should enclose equal areas. In either case, however, the curves do not represent exactly identical conditions because lifts were made at least 6 minutes apart, for the west side and 10 minutes apart for the east side. It is seen, however, that in each case the area...s are almost exactly 36 equal wbicb proves that the motors operate effi- ciently in parallel. If both elements of the wattmeter bad been intact, a further test of the action of the two motors under parallel operation, could have been made by connecting both motors to the in- strument and then allowing first one and then the other to record the power used. This method is fully described in the results of a series of tests made upon the Webster Avenue bridge by A. L. Scbreiber and S. H. Miller • 4.
