reactive centrifugal force peng/lu

Postby everything on Tue Dec 16, 2014 3:10 pm

The diagram describes a theoretical example of a ball tied to a string and in rotation around a post. Basically a circular motion creates an incoming force and a balancing centrifugal force. Similar to peng/lu, incoming force is borrowed (lu) circularly to create centripetal/centrifugal force (peng). Although the string is under tension and your arm (for example) needs some tension, there is net zero force on it (in lab/theory) since the in/out forces are balanced: "no force" with no qi concept required in the explanation.

Already an orthodox description of this Cai Lang method you describe in many styles of TCC:, no need to reinvent the wheel:

FAN TENG LANG –Churning/Turbulent Wave – centripetal force followed by centrifugal force.

Cool yup. Physics is physics so nothing for the MA crowd to reinvent but I hadn't seen the "reactive" phrase.

The zero force part is perhaps more interesting. No b.s. explanation of this phenomenon.

Yeah that's real nice but how many people do you know that can actually utilise his principal naturally without thinking in their art? ;)

There is no applicability to this, it's irrelevant, it adds nothing, it clarifies nothing. It's a crutch for those not actually training.


Apart from that, there's no such thing as centrifugal force.

Huh?

I think most of us have felt it in ph or grappling sports many times. But not bothered with various words or physics study. :shrug:

This. I'm all about the physics (and mechanics, and anatomy), but it only works as a model if folks understand the meaning of the words they're using.

That's a pretty retarded statement, I find it offensive too, as I'm sure it was designed to be taken.
Nine the less, my student Marc Crowe spent 6 months training cai lang methods with me for moving step tuishou. He had been getting nowhere for years as he will tell you himself. Nowbhe it the Irish national champ innopen weight and hot a silver in the British.

Like anything is not practiced it amounts to empty verbalage, if trained it is effective. You have trained practical tai chi and you should therefore know that the skill is held to be one of the highest atainable, with specific training methods and drills. That's a lot of good tcc people to contradict ! But be the genius!

As for using it without thinking, anyone I've trained seems capable.

I was talking to willy, but I'm glad you gave your guy a shaky understanding of cod physics and now has a national champ in two countries.

Apologies, I misunderstood, and I guess you might have too, as I dont give physics classes. Just coaching in applying cai lang methods. That involves repeated application practice, free wrestling with focus and orthodox tuishou drills. All with progressive resistance, nothing that strange really.

"That's a pretty retarded statement..."

Not picking a fight here, but as long as we're registering offense, I work with the mentally disabled. It's not a kind term.

What because it's the fictitious force and is only observable when there is motion. It is true in an absolute sense but not in a relative. I still train so I guess you must be referring to something else. :D
