| contd :- -3- The appended curves illustrate the widely different frictional conditions which exist when 'parking' and when experiencing 'joggles'. They are the average of a number of nuts and worms, all have the same characteristic. We have no difficulty in reproducing the results with regularity. The main point is that if the conditions of movement were the same for 'parking' and 'joggling', the steering would be for all practical purposes irreversible as indicated by line d.{John DeLooze - Company Secretary} Actually, however, line c. represents joggling conditions. To bring line c. down to line d.{John DeLooze - Company Secretary} the efficiency of the steering when 'parking' would have to be impossibly low.
