Physics problem - please help!
I have absolutely no idea wat this question is talking about.
Young’s modulus for bone is about 1.4 x 10E10 Pa, and bone can only undergo a 1.0% decrease in length before fracturing, so
(a) What is the maximum force that can be applied to a bone whose minimum cross – sectional area is 3.0 cm², without fracturing? (This is the approximate area of the tibia at its narrowest).
(b) What is the maximum height from which a 75kg person could jump without fracturing the tibia? Assume that stress is the same in both legs, and that the time between first touching the floor and coming to rest is 0.035s.
Thanks for your help!
