| To Hs.{Lord Ernest Hives - Chair} from Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} X5370 Hs{Lord Ernest Hives - Chair}/RnL/LG17.6.25. 'INDIA' SERVO. We have tested the efficiency of this servo. We find that the average torque multiplication is 1.24. The extreme variations in the servo efficiency are from a torque multiplication of .93 to 1.46. The efficiency of this servo appears to vary more with the speed of the car than with the method of application, the higher the car speed the more efficient the servo. This servo is fitted with 45° cams of .7" mean radius and the servo was lined with Ferodo. COPYRIGHT 1904 MADE AT CROXLEY Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
