E(E — e) 153 R and that converted in the motor is e{E— e)R Now the area of the rectangle F K D C = E (E — e)and the area of the rectangle G B… … graphically two of the problems which have already beentreated analytically in the first chapter (page 39). Theseare the following : First, what is the condition of maxi-mum work obtained from the motor ? and, secondly, whatis the condition of maximum efficiency ? The answer to the first question…
