| contd :- -4- trying one out experimentally with loads as indicated in the sketch below :- [Graph text] Left axis: Lbs. load pend:lever end, with values 30, 20, 10. Bottom axis: Ang. mvt. pend:lever., with values 30º, 20º, 10º. Inner horizontal axis: Ang. mvt. pend:lever o, with values 10º, 20º, 30º. Inner vertical axis: Lbs. load pend:lever end, with values 10, 20, 30. We have fitted two 40/50 HP. cars with friction in the column. The results are good but we have not yet done sufficient running to determine the effect on high speed wobbles, a difficulty which does not occur on the 20 HP. Summarising the situation. The experiments were undertaken because we have several owners of 20 HP. cars (notably Mr. Flather) who are inveterate complainers and whom we cannot satisfy with regard to 'joggles'. They quote other cheap contd :- | ||
