How so?Top on the CB reduces the amount of sideways friction, which should reduce throw and skid. The CB sliding in the cut direction isn't a problem.

Actually, I did. Straight back, underneath. Only made it about 20% of the time, though. I haven't picked up a cue in about a month, and I'm not stroking it very well. I mean, I know exactly what I'm trying to do, in order to make the bank, but I'm just not executing the shot. I guess I need to get back to the table.Did you bank it yet?![]()
Say what??By making the rubbing direction more vertical.

There is vertical gearing as well; causes cling/skid...Say what??
I will agree with your statement in #102, but not this. TOP will change the speed of whitey making less contact with the OB, thus inducing Less gearing/throw. That is just physics. The slower the speed; the more the throw , more speed reduces throw.
The balls make contact at the horizontal axis. The only exception would be when the CB & OB are at different heights, (ie: like jumping balls).
and there are outside influences .... dirty hands from that greasy fried chicken snack from 15 minutes agoThere is vertical gearing as well; causes cling/skid...
The friction force is limited by the force between the balls and the coefficient of friction. The most sideways throw (or skid) happens when the slip of the cue ball is horizontal. Follow changes the direction of the slip to be partly down and the throw force is divided between sideways and down. That means that the sideways force is less.Say what??

I suppose you mean vertical rubbing. "Gearing" is the absence of rubbing.There is vertical gearing as well; causes cling/skid...
LOL,sheesh .... so many scientist
rarely .... it is usually because a 4 in league really cant consistently do anything ... even with a cue that hits a ton with or without a cf shaftLOL,
How many times in league did you see a banger completely miss a simple cut-angle shot they slow rolled???
Then they have this look of total disbelief becausethey could of sworn they AIMED center pocket. They missed b/c they slow rolled for center pocket and the Gearing/throw made the ball miss center pocket and hit the point of the pocket.
Science meets sport,.....![]()
When the balls snag that's gearing.I suppose you mean vertical rubbing. "Gearing" is the absence of rubbing.
And vertical rubbing doesn't cause skid - if anything it just causes the CB to slide a little in the shot direction. Skid is caused by excess horizontal friction causing the CB to throw more than usual across the shot direction.

That's not the usual definition of gearing. It usually means the surfaces rolling across one another with no rubbing or friction, specifically to prevent "snagging",When the balls snag that's gearing.
Banks are a “feel” thing and when they are working it’s the best! When they aren’t it’s difficult. Seems either the all the banks are “open” or “closed”. You’ll get there, I too haven’t been playing much and they are most likely “closed” for me as well. They will open with a bit of time and getting that feeling again.Actually, I did.

Isn’t CoF a measurement?"skid from throw" is practically moot in such a slow speed and short distance. You can likely measure it in nanometers. As far as co-efficient of friction,... we are talking 2 objects of like(same) material. COF comes into play from rigorous friction of like or dissimilar materials. More a factor of wear than contact.
I feel like we are splitting atoms with a butcher knife, lol
I'm not sure how you'd measure it in nanometers, since it's an angular difference (intended cut angle vs. actual skid angle)."skid from throw" is practically moot in such a slow speed and short distance. You can likely measure it in nanometers.
Ban....Follow changes the direction of the slip to be partly down and the throw force is divided between sideways and down. That means that the sideways force is less.
