| R2/M21.4.31 contd. -2- We might also build a chassis with entirely different side members. The same depth heavy might not alter the periodicity, but deeper ones should. Weight and tie-rods might say something, and different rubber in the feet. If we can get the reason of the periods we might quickly do something. R.{Sir Henry Royce} | ||
