| To Hl. from Hs {Lord Ernest Hives - Chair} /Tsn. X8000 Hs {Lord Ernest Hives - Chair} /Tsnl/LG29.8.28. COMPARATIVE RIGIDITIES OF CRANKCASE MATERIAL. X8000 X.3992 The materials for which we should like you to measure the Young's Modulus of Elasticity are as follows :- Grey cast iron. Hard white cast iron. Aluminium alloy (ordinary crankcase alloy). Our new light alloy L-25. 'Y' alloy (cast and forged). Duralumin (forged). Aluminium bronze. Any ordinary bronze. We presume that you will require machined test pieces; please let us know whether we can make them for you, and to what dimensions. Hs {Lord Ernest Hives - Chair} /S.S.Tresilian. | ||
