| -13- Hs{Lord Ernest Hives - Chair}/AFM.{Anthony F. Martindale}2/Kw.27.7.36. (18) Next we tried increasing the inertia of the N.Scheme by adding weights as shown. We found that if we added 15 ozs. of weight at 4" radius (15 lbs-ins.² M.of I.) that using stiff drums thumps disappeared and judders were very difficult to get going forwards. Owing to the considerable weight required to obtain this partial success, we do not regard this as a very practical cure. It judders easily on reverse. FRONT OF CAR | ||
