In desperate need for an answer with regards to Bones!!!?

Question

OK...

My question is how much downward force/velocity is necessary to break a bone in one's leg (preferably the weakest bone).

Please give answer in m/s or N

thank you!

Answer 1

There are so many variables between the weakest bones on different individuals that its hard to give a precise measure, but according to what I've learned in Karate i would say 14lbs.

Answer 2

I don't believe that bones exist and I think this is a conspiracy devised by anatomists.

Answer 3

3 pounds of pressure

Answer 4

I have seen bones broken from falling down from a standing position or while walking.  People who have unhealthy bones are in danger from small forces.  Variables also include the angle and location of the force.
