| -3- Hs{Lord Ernest Hives - Chair}/FJH.{Fred J. Hardy - Chief Dev. Engineer}25/KW.13.9.35. In future tests on the vibrating machine we shall have to take readings at closer intervals in order to locate the resonant frequencies more accurately. The resonant frequency will be the best means of judging the effect of alterations to stiffness as the amplitude obtained depends upon the magnitude of the impulse applied and therefore the setting of the machine. Closer regulation of speed is also desirable. Hs{Lord Ernest Hives - Chair}/F.J.Hardy. Additional Tachle. £14. Run spectreCodename for Phantom III on this rig | ||
