hmmmm
I'm still a little confused. The answers posted seem to indicate that due to the inclination forward of the disc, hookes joint effect will cause the advancing blade to lead. yet the question seems to indicate that it lags. the books are good at describing how the blades behave in a hover, and in a hover with the disk just tilted forward, but are light on what happens regarding leading and lagging in forward flight.
so, in forward flight, is the question correct, does the advancing blade lag? and why?
thanks!!
