in equation (iv), wehave (V) F = That is, the power output of machine B is proportional to OQand the proportionality factor is the constant BjV R -\- X^. Equation (v) may be put into a more convenient form as follows : The projectionof A, Fig. 192, on the line ef is equal to A cos ((/>—^) ; the… … Fig. 193. Figure 193 is a construction essentially similar to Fig. 192, but with the electro-motive force A taken as the fixed reference axis ; both Figs. 192 and 193 beingconstructed for the same value of 0. From Fig. 193 it may be shown that P. A. OQ V R^ + X-^ (vi) from which an expression for P…
