Hi Charles
Dunno what your level of knowldge is but...I have an ancient textbook which is far far smarter than me;
You can compare stresses one form to another, assuming eveything is rigid! on the lift flank
accel= w sqd (rbase+rfollower) (1+2tansqdA)/cosA where w is angular vel in radians, A is angle turned past tangent opening point.
With a flat follower theoretical accel is infinite......
When I was supposed to be digesting this stuff eons ago, if they had related it to Sevens i might have absorbed some of it at the time and not just 55 years later!
Too late in the day here to sort out proper symbols.
The critcal point is intial lift where accel just wsqd(rb +rf)
(for others, all else equal, loading is proportional to accel)
