The second question i have is regarding equation 7.8, the rotor width (w) is reffering to the length of one flank or the actually thickness of the Rotor?
Im just a bit confused in what direction i need to be going in as the e/R ratio cannot be determined for rounded flanks unless the (As) value is known equation (7.16)
All above questions are based on the chapter 7 article, any help would be very much appreciated
thanks.
