| R1/M5.5.30 contd. -2- road vibrations that reach the body from the frame. We have then :- (1) The power unit and gearbox insulated from the frame (rubber). (2) The body insulated from the frame (rubber) (3) The passengers insulated from the body (good cushions). All of which are possible and should be uniformly carried out. This has not much bearing on booming, which may come through the air. R.{Sir Henry Royce} | ||
