Math Problem for skating

[Sk8Bunny]

In my trigonometry class this semester, we have a project due where we must take a formula,theory, or something of trig and relate it to the outside world. We can choose anything, including a career. I want to show how a skating element has trig involved in it. However, i cant find any info on the web to even begin to figure out if skating DOES have trig involved in it. Please help me! I would really like to use a pairs lift as the skating element, but if anyone has any ideas or anything that may help me, please share! Thanks sooo much!!

you might find your resource right here on this forum:

http://www-personal.engin.umich.edu/~gcoch/jumpphysics/jumpphys.html

and on to: "open and closed moments of inertia"

http://www-personal.engin.umich.edu/~gcoch/jumpphysics/inertia/inertia.html

this was written by gary cochran at u of mich. i think this is the very same gary cochran who is melissa ralph's gram'pa who is in the engineering department at u of mich.
but i'm not positive.

give it a try, if i'm right, i'll bet he can help you. (even if he is isn't one and the same who wrote the info on the above link.)

so do a search for "melissa ralph" and his name (which is his screen name) will pop up, you can pm him or e-mail him from his listing.

have fun. let me know if this works out.

If I am not mistaken, there is a link on the SkateWeb site entitled the Physics of Skating. That may provide some information for you. Good Luck!

Before we can help, what level Trig are we talking about? Jr. High, High School or College? Makes a big difference.

Im a high school student, but taking my trig class at the local community college. So its not quite university level trig, more like in between high school and university level.
