WOR.{Arthur Wormald - General Works Manager} Hs{Lord Ernest Hives - Chair}1/L019. 8. 24. X9910 X2628 RE: NIP IN ROAD SPRINGS. We attach herewith two charts showing the amount of friction measured on the road springs which were on 46-PK car - EAC.11, open touring. We also attach a sheet giving the amount of nip between the leaves. We have taken several other springs apart and find that the total amount of nip is approximately the same. On the average there is very little nip except between the 1st. and 2nd., and the 2nd. and 3rd. plates. Hs.{Lord Ernest Hives - Chair} | ||
