| contd :- -4- We are preparing some notes on the method we employ for estimating the resonant speeds of six cylinder crankshafts with the influence of various factors on the same. In both cases investigated we have found the method to be quite reliable and in close agreement with our practice investigations, and observations. -------------------- | ||
