Agymnast does a one-arm handstand. the humerus, which is the upper arm bone between the elbow and the shoulder joint, may be approximated as a 0.27-m-long cylinder with an outer radius of 1.12 x 10-2 m and a hollow inner core with a radius of 3.9 x 10-3 m. excluding the arm, the mass of the gymnast is 60 kg. bone has a compressional young's modulus of 9.4 x 109 n/m2. (a) what is the compressional strain of the humerus? (b) by how much is the humerus compressed?

![= \frac{(60 kg)(9.8 m/s2 )}{(\pi)[( 1.12\times 10^{-2})^2 - (3.9\times 10^{-3} m)^2] (9.4\times 10^9 N/m2 )}[tex] [tex]= 1.80\times 10^{-4} m](/tpl/images/0380/8166/4e6b8.png)
