Class, keep in mind that
the distance from knob end
and median handle taper
is dimension V with Y Degree
of taper from knob to handle varying by X.
Dimension W is the distance from knob base
and diameter at Segment T,
the thinnest area of the bat handle.
Dimension S is the throat area between
the handle and the median barrel taper,
with X distance from the knob base
and X and Y diameters varying inversely.
Knowing that Dimension Z is a defined
distance from the barrel end,
you should have no problem
hitting the curve if you remember that
rotational velocity is indirectly
proportional to tangential velocity.
