adily through the field, i.e. the angle a^TTvaries from o° to 360°, and, since the value of the product ja. B is proportionalto the square of the angle a^Tr, its mean value can be found in exactly thesame way as the mean power was determined in Section 73. Analogous toequation (115) on page 237, we… … Fig. 398 of effective wire in the coil-side. Since, however, the same mean force isgiven by every coil-side during a period, the total tangential force on therotor is equal to /, where A J. B. «2 sin vTT „ , , , , /= -. —^—.Z,./: dynes (173). This force acts at an arm equal to the rotor radius r.…
