Did I do the forces right?

Did I do the forces right??

Hiya,

So what I have here are two images with stick figures on them showing the forces.

I have to locate the center of mass on the real picture, inked in red and then using the stick figure, locate all the external forces acting on the system. The system in both is just the athlete involved.

Did I do this right? I'm just a bit confused on finding the center of mass...esp in difficult poses. Also is the reaction force also called the applied force? :yuck:

Thanks for the help.

 

Any type of suggestions are welcome, please :\

 

Ahhh, I see why. No wonder lol.

Here are the links:

Snatch

and

Shaolin

Thanks.

 

Anyone? Much apprec. if I could get a yay or nay ;P.

 

Even my center masses! Alright! That's cool. Well, Shaolin monks are nutty, they do the wildest things so it could be possible for them to just hold it there lol. Maybe if I drew the leg straight, then I could just make an up arrow and it'll be less ambiguous.
Thanks!
