Oh yeah, i forgot, Heiny was going to start correcting loosly used terms again.
Sorry, yes, acceleration is the first derivative of velocity with respect to time.

SPEED =not VELOCITY

Speed is how fast an object is traveling
velocity is speed in a particular direction.[
acceleration is the second derivative of DISTANCE in respect to time.
Anyway, i think in our discussions, use of "common" language can be used as we are not writing theories here, we are trying to understand priciples. You never did correct idea that there are trade offs over an operation an operational range in a gear ratio change (all other things being equal). Depending on the speed range, different gear boxes will have their own advantages. (ie 0-155, 0-115, or 48-155mph, etc, etc). You cant say that a GT ratioed box is the best gear box for all applications. this my only point.
You kind of remind me of Rainman. Able to count those toothpicks in a nano second, but have no idea what a toothpick is used for!
If you drop the ego for a second, realize my only goal was to show the real effects of gearing over all speed ranges.
oh, by the way, sorry about the "Heiny" didnt think about the dual meaning!. (ie like don H. calls me Marky)
