80's heavyweight powerpunching tournament

[Brockton Lip]

I also heard that a heavyweight hits with the force of an air bag from a car. But I also heard that they average around 600 psi.
I am very curious as to which is true, if either.

look this is it!!
"I was wondering if anybody knows what the average boxers punch rates in lbs.psi and what tyson's punch rated. I read somewhere a mule can kick and hit at 500 lbs psi and tyson was 300 lbs psi or something like that. Thanks"

psi=pounds per square inch
lbs=pounds
lbs psi=pounds pounds per square inch

Anywho PSI or pressure is calculated with the equation Force/Surface Area

Surface Area of a boxing glove is what? Anyone wanna guess? I'll take a stab and say somewhere around 14 square inches.

300=Force/14
300*14 gives us a force of 4200 pounds
Force, in this case 4200, is equal to mass times acceleration.
4200=M*A.
F=M*A is in the units Newtons = Kilograms * Meters/Second^2
1 pound equals roughly 4.5 newtons
4200*4.5=18900
18900=M*A
I don't really know how quickly Mike Tyson's punches accelerated, nor do I know how much mass was being accelerated at that rate. However a good puncher is able to put more weight behind their punch, but obviously it won't be too much of their weight so I'm gonna guess and say he can get 1/4 of his mass moving towards his opponent, and at his prime he fought at about 220. That means 55 pounds, 1 Kilogram=2.2 pounds. That means 25 kilograms.
18900=25*A
18900/25=756
And we find that according to me Mike Tyson's punches accelerated at 756 meters per second squared. That sounds crazy but wait. Actually it sounds very crazy. That's accelerating at like 2 miles per second. But thats if he is accelerating his mass for one whole second. I once again am gonna guess and say he takes about 1/12th of a second to punch. So divide that 756 by 12 and we get a velocity of 63 meters per second. Sounds much more reasonable. Now I have managed to prove nothing more then that I have waaay too much free time on my hands. Oh well. Hope that helped put into perspective how realistic/unrealistic what you heard was. Anyone else got input or feedback cause Tyson is my favorite and I'd love to find out if anyone knows what his punching power actually was, if it was even ever tested.

P.S. I've used my physics "expertise", if anyone here has computer expertise and a file containing Mike Tyson punching, perhaps we can find out more accurately, as opposed to my guessing at everything that was unknown, and guessing one at a time leaves all the minor faults to add up and make the last value quite possibly fairly inaccurate.

WHAT! 300PSI ARE YOU NUTS!!

I find it hard to belive that Mike Tyson punches as hard a an out of shape and fat 190lbs person.

The average heavywieght punch is 800lbs. Mike's punch is WELL ABOVE average. Also, these tests are taken GLOVED. There is a significant difference between gloves and bare fists.

It is about building devices to measure the power of a punch and lists the force created by advance, intermediate and beginner punchers.

ABSTRACT:
The development of sport-specific dynamometers is an important step towards ecological validity in analysing athlete performance. Design limitations in previous punch-measuring devices have resulted in values which may not or cannot fully reflect the force and multidirectional components in a punch. In developing this boxing dynamometer, a triaxial force measurement system and a boxing manikin interface were combined. The repeatability and accuracy of the dynamometer were assessed using simulated straight punches. Discrimination efficacy was assessed by comparison of the maximal punching force of seven elite, eight intermediate and eight novice boxers during simulated boxing, throwing straight punches. For the elite, intermediate and novice groups, respectively, the maximal straight punching forces (mean plus/minus s x) were 4800 plus/minus 227 N, 3722 plus/minus 133 N and 2381 plus/minus 116 N for the rear hand, and 2847 plus/minus 225 N, 2283 plus/minus 126 N and 1604 plus/minus 97 N for the lead hand. For all groups, maximal forces were larger for the rear than the lead hand (P < 0.001). Maximal punching force was greater in the elite than the intermediate group, and greater in the intermediate than the novice group (P<0.05). The boxing dynamometer discriminated effectively between punching performance at three standards of performance and between the punching force of the rear and lead hands.

"The average heavyweight boxer hits with 700 pounds of pressure per square inch. Drago averaged 1,850, and even hit 2,150, which is the equivalent of getting whacked by Mike Tyson (who I would say is pretty average right about now)"

Mike tyson dosent have average power now, power is the last thing to leave a fighter .

[blockhead]

i dnt think thats a reliable measurement.. tyson ko bruno into oblivion...

he tko'd bruno and bruno stuck with tyson for about five rounds longer than expected.

"There are 100 different acronyms for the different bag systems," says Lysholm, "especially the new ones. As for location, in the BMW, the air bags come out of the headliner and across the window from the A to the B pillar. Mercedes Benz and Volvo now have an air bag about half the size of an air mattress that comes across from the A to the C pillar and across all the windows. The inflator module is in the C pillar, with about 3,000 psi "

WASHINGTON -- Pressure to rapidly address the dangers air bags pose to children -- heightened by the addition of a Houston 2-year-old to the federal air-bag death toll Thursday -- is about to collide with technical complications.
Automakers are worried that unforeseen problems could result from the rush to prevent deaths such as the December decapitation of Montrey Jones, which increased the number of children killed by the safety devices to 35.
