What are your initial thoughts? We need to see something from you on questions #2 and #3 in order to help you. What forces and timescales are involved?

All i want to find out is the approximate stress for each step that a person takes.

I need to keep it quite simple for a presentation that i am doing so i was going to try and estimate the force that is produced on impact with the floor and then divide that by the approximate cross-sectional area to find the stress.

I just need some help with the approximations.

Any help appreciated

well the actual force would be hard to approximate because it varies from person to person due to mass change.. at least that is what i would think
