Threw shot and hammer today, nothing extraordinary as far as distances go, ~15.40 shot and ~49 hammer.
Did some calculations when I got home to see why hammer throwing is so tiring. Making silly assumptions like no air, hammer released from ground level, optimal angle of release, 2 dimensional circular orbit, etc. I was able to come up with a simple formula for the force needed to counter a hammer throw of a given distance, F = d*w/r where F is the force in pounds, d is the distance thrown, w is the weight of the hammer and r is the radius of the orbit. For a 160 foot throw (~49m) using a 5 foot radius this gives a countering force of 422.4 pounds for a 6kg hammer. No wonder I’m so tired.
Read an article a very long time ago where they had done the same type of calculation on some of Harold Connolly’s throws. He was over 600lbs. Amazing thing was the withered arm he was born with and had repeatedly messed up. The current WR throw must of be 800+?
PS If anyone is reading this and doesn’t know who Harold Connolly is you’re a heathen.
Yeah, it comes out to around 775 for the world record, but most of the assumptions which make the formula simple underestimate the velocity needed to throw a particular distance, so the actual force is probably closer to 800.
An interesting thing about the formula is that is shows force is inversely related to radius. Same distance with larger radius = less force to counter, besides a slower angular velocity. Increase the radius and the ball will go further with less effort.

I’m really glad you understand all that because if you were looking for help…

So you just figured out why slingshots and trebuche work as well as they do. And why a guy who’s built for deadlifting should be a good hammer thrower…
Cool.
Ya geek. I mean that affectionately, being one myself after all.

Here’s how geeky. I knew long radius was good all along, and for pretty much the reason that the formula makes so clear, but until I had that silly formula in front of me, I wasn’t really convinced.
Its too bad the 3rd derivative doesn’t have much to do with what goes on in a hammer throw. Then I’d really be excited.

I guess there is a reason why I dont throw and placed into 9th grade algebra my freshman year in college…

I was just making fun of myself for being such a geek. I’d be glad to see you pick up a shot or hammer. Converts, you know.

HAHAHA! I’d like to try a hammer. I could pee farther than I can chunk a shot, Carl. I did it a little in high school never was succesful. I did a better job of knocking linebackers down than throwing.

Knocking linebackers down, that sound fun. Hammer’s even funner.
An infinite number of mathematicians walk into a bar. The first one orders a beer, the second orders half a beer the third asks for a quarter of a beer. Before the next one can speak, the bartender says “You’re all idiots,” and pours two beers.
I just need a second here to thank you Carl. You have expanded my knowledge and understanding of OL by ten fold. Your use of videos is a great benifit. Thanks again!
