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?

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
