@Archo: PNut's theories where not the problem. His physics was spot on. He just wasn't doing what he thought he was doing.
On the other hand, I have a feeling that your theories are off and, at the same time, you are not doing quite what you think you are.
In any case, kind of cool how all your technique miraculously fixes itself when faced with the prospect of posting video. LOL.
It's all good. If there are that many defense mechanisms against posting, no need. The only person harmed would be the person who stands to learn something. But....
Oh and by the way, if you are training with someone, and you have a friend hold your phone and film you and NOT the person you are hitting with, then the other person does not have to worry about whether you are being filmed. Because they are not being filmed. So you don't need someone else who is willing to be filmed.
A friend filming for 3-5 min from a few different angles that allow you see what you are doing clearly, would help you a pretty decent amount even if you didn't post it here. Analyzing footage of yourself is really worth doing.
So, the car tires slipping and screeching because of too much tangential force causing the tire rubber to fail, the weight of the car, the force against the ground, the fact that the car cannot move the ground, these things combine to cause a scenario that cannot happen with something as light as a TT ball in flight in mid air. If you put the racket on a surface like a table, and too the ball in your hand and pressed into the rubber, and then applied tangential force (pushed to the side) you could get the ball to slide in a way that caused the rubber of the topsheet to fail. And then you would be buying yourself a new rubber.
In TT when the ball slips on the rubber, it is not because of rubber failure but instead because of not enough contact, so the ball slips off. Usually the ball doesn't really go where you were expecting when that happens.
When you loop, what you feel is the rubber grabbing the ball. There are a variety of sounds you could here from that happening. I think what is happening when you feel the rubber grab the ball is something like this: the ball depresses the topsheet and sponge. But there is also a tangential force which causes the rubber to stretch and distort in the direction of that tangential force. When the ball sinks in and distorts the topsheet as it stretches it tangentially, more of the topsheet wraps around the outside of the ball (more grab).
When you add the tangential speed of the racket to the rebound of the stretched rubber it seems this is where most of the spin comes from with a good loop.
And if the rubber does grab the ball, there will be no screeching sound. And my guess is that the imagined rubber failure and screeching sound could easily have been birds flying around the table or the squeaking sound of your shoes on the ground.
But nice how quickly you are looping ever different kind of ball that comes at you. With such speedy progress you will be 2700 in no time. [emoji2]
Glad we got you to learn correct technique so fast. LOL.
