Thank you!

I have only a very basic understanding of vector forces in the context of hanging loads - for example, a weighted object anchored from two points, the internal angle between the two lines from those points to the load determining the actual force each line must support. What I don't know is if...

Awesome. That helps completely. Thanks a lot. by the way, your estimation of center of mass is pretty good - 55-56% of height is the general rule among kinesiologists, et al.

What I meant by percent moved is, say I weight 85kg - that 85 kg is obviously not all located at my shoulders, although the majority of it is pretty close. In a full push-up (sternum travels from floor to 20 cm above the floor), how much of that 85kg was moved that 20 cm? I can figure out...

I'm trying to determine approximately how much (percentage) of an athlete's body weight is moved when doing a push-up. I know it's a second class lever, but the lever itself is the load, and worse, the load is not evenly distributed along the length. I know approximate body segment weights, but...
