With reference to the above, the following is an extract of Mr. Royce's memo R12/B14213. :- " In testing the strength of the back axle by the bumping (by log) I have the impression that we used the present system of inverted springs to control the axle sideways, and that they performed this duty without shewing any distress or the axle shewing any signs of moving sideways due to their want of control. If, however, the 3/4 eliptic were used, please at once arrange a test to be made on our present standard springs and fittings. a new light axle might be used in this test - 2 tests in 1. Will you kindly let me know what type of springs were used on this experiment? P. A.{Mr Adams} Wormald. x137 | ||
