| To E.{Mr Elliott - Chief Engineer} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} +5640 Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}1/KT.1.5.33. We have carried out one or two tests on pistons with a view to determining the stiffness at various points, and the load sustained before taking a permanent set. We are not sure that these figures are of any value but give them to you as a matter of interest. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
