| K.W.33 To H.C. Ha/Gry.{Shadwell Grylls}17/KW.26.10.34. 4-Bearing Engine. We find in comparing the figures of stiffness and inertia of the 4-bearing shaft with previous results that we have not got any figures for the latest Bentley production crankshaft. Will you therefore please let Walter Gell have such a crankshaft in a crankcase in order to obtain a torsion test, and also the moment of inertia of the shaft. Perhaps you could arrange this when one of the test bed units is in pieces. Ha/Gry.{Shadwell Grylls} | ||
