BIO Compression of Human Bone. The bulk modulus for bone
Chapter 5, Problem 31E(choose chapter or problem)
BIO Compression of Human Bone. The bulk modulus for bone is 15 GPa. (a) If a diver-in-training is put into a pressurized suit, by how much would the pressure have to be raised (in atmospheres) above atmospheric pressure to compress her bones by 0.10% of their original volume? (b) Given that the pressure in the ocean increases by 1.0 X 104 Pa for every meter of depth below the surface, how deep would this diver have to go for her bones to compress by 0.10%? Does it seem that bone compression is a problem she needs to be concerned with when diving?

ANSWER:Solution 31E Step 1 of 4: V Bulk stress is pressure change P , and bulk strain is fractional volume change( V ), The elastic modulus is called the bulk modulus, B. That is, B = Bulk stress Bulk strain B = V ………...1 V
