Graph 1. is intended to illustrate the effect of flexible springs in reducing the accelerations imparted to the body, and also to emphasise that wavy roads with rises of considerable length, can produce unpleasant riding in the car. A hump-backed bridge is a limiting example of a long acceleration causing acute discomfort. (c) Periodicity. If a number of persons get hold of the back of a car and move it up and down, it will be found that quite a large contd. | ||
