| 5. So we get from each test, the front wheel steering angle, the front wheel slip angle, the rear wheel slip angle, and the roll angle. To make good diagrams these should all be plotted, not against speed on the curve, but against lateral acceleration in terms of g, i.e. .1g, .2g, .3g, .4g, .5g, .6g. Six tenths of g is about maximum we find for steady cornering on dry concrete. In making tests the driver has to hold the car on the marked circle as closely as possible, and keep a steady speed. The front passenger has to make the steering angle readings. The rear passenger has to sight on the post and can make his readings when the car is brought to rest after the test. Practice on the part of the driver is essential. We find that the actual radius of turn | ||
