| Cont'd.{John DeLooze - Company Secretary} a.{Mr Adams} .550 ins. prop. shaft pumping on max. bump. b. 4.7% understeer under full load. c. Zero understeer with 2 up in front seat, assuming .875 in. deflection for the removal of the rear two passengers. 9. The front end of the rear spring, being under the frame, is virtually a fixed limitation. The height of the rear eye is controlled by quantities outlined in 'S'. It is impossible to provide a tension shackle of reasonable length to approx. the constant periodicity with varying load without imperilling the ground clearance. It was agreed to use a long compression shackle which will give equivalent results and provide an easier and lighter construction. 10. Rm{William Robotham - Chief Engineer}/CB. will go ahead with projects of the front and rear spring fixings of the rear springs so that we can determine the shape of the frame side member. | ||
