| Hs.{Lord Ernest Hives - Chair} from DA{Bernard Day - Chassis Design}/Hdy.{William Hardy} X 8005 DA{Bernard Day - Chassis Design}/Hdy{William Hardy}1/M2.3.28. ENGINE TORQUE VIBRATIONS. X. 8005 X. 634 I give below a sketch of the damping scheme referred to in R3/M19.2.28., in order that you may know what is intended, and be able to test it temporarily should torque vibrations again come into prominence.
