| -2- Mr Spinney 18.4.12. arranged on the ends of these ropes in such a way that if the steering wheel be turned in one direction one weight will be lifted and if turned in the other then the other weight will be lifted. The loads [handwritten above 'ropes'] ropes should be arranged so that the steering gear would be stressed to about 50 % to 66 % of the elastic limits of the weighted parts. In running the tests the steering gear should be turned almost to the full lock in either direction from 10 to 100 times. This testing tackle will be used on every standard car during its ordinary test. | ||
