Re Steering Pivot Tests
X. 168

I think that it is quite evident that the pivote will not break from the torsion, but I think that the reversal test was not the best test that could have been devised to prove whether the thickness at the point shewn on the diagram was dangerous, because this thin place would be more likely to fail by road shock /s than by simple torsion developed by the reversal rig shewn.

I think that it would be worth while to make such a pivot extraordinarily thin, say one-tenth inch under size and test on the track as this ought to make us quite happy on this particular point
