View Full Version : An Amusing Lesson in Physics and Structure

Sifu set me up.

Seriously.

It's not my fault.

After an auspicious evening that began with me taking and passing my blue sash test, we did some of our usual warmups and chain punches only to be treated to an object lesson on the importance of proper structure in the reciprocating vertical punches that are one of the primary weapons of Wing Chun's arsenal. Sifu Anthony offered a five-foot bo tp the assembled students and asked who'd like to take a swinging strike at a couple of "rebreakable" plastic boards set up on phone books on the floor.

I, of course, volunteered. I consider myself no slouch when it comes to weapons technique.

Sifu used another staff to limit my windup in order to make his point. I struck the boards -- I didn't realize there were two stacked up until afterward -- and succeeded only in transmitting shock to my left hand.

Sifu then, using only two fingers, used the staff vertically to break the boards with little effort. The lesson in structure and physics was obvious. Chain punches, to be effective, must be delivered straight -- not in an arc, not looping over or under.

Then he set me up. "Here, Phil, you'll want to redeem yourself," he said, handing me the staff again. "Wind up as much as you want." I lifted the staff to the ceiling and took a mighty swing, intent on blasting through the boards with tip of the staff as I brought it through its arc.

I'm told the look on my face was quite something to behold.

"I knew that was going to happen," Sifu told me when I stopped sputtering.

Howdy Phil,

Not to put a bee in the ol' bonnet, but what of angular momentum the high level of force that can be delivered in a small amount of linear distance?

And there is the whole bit about the alignment of the wood fibers which are ment to take a compression load vs. a shear load. Yet human bone is under tension and compression as well as having a more complex matrix to redirect a wider variety of forces.

But yeah, I love those sort of demo's too. They usually happen just after I thought I'd figured everything out. How do they KNOW that? :)

Well, yeah -- that's why it broke. ;)

Phil-

Sounds like your Sifu and my Sensei have the same sense of humor :lol: ! Very interesting/entertaining story!

Congratulations on your promotion, keep up the good work!
