| contd:- -3- The co-efficient of friction determined from our front brake results, taking into account the wrapping action, is .427. Ferodo's said that this figure was quite reasonable. Taking µ = .43 the EAC.111. Servo would give an increase of pressure of approx. 16 to 1 against 17.5 to 1 determined experimentally. Hs{Lord Ernest Hives - Chair}/ACLovsey. | ||
