| X8380 To R.{Sir Henry Royce} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} C.C. BT.{Capt. J. S. Burt - Engineer} W.Or. E.{Mr Elliott - Chief Engineer} DA.{Bernard Day - Chassis Design} BY.{R.W. Bailey - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rml/LG23.5.28. FRAME TESTS. X8380 We attach herewith two further tests on the 'X' shaped cross member. The bending test does not seem to have a parallel in actual road conditions but we think it may be of interest. The shear test again indicates the great rigidity of the 'X' member. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
