Question

A gymnast 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 $0.30-\mathrm{m}$ -long cylinder with an outer radius of $1.00 \times 10^{-2} \mathrm{m}$ and a hollow inner core with a radius of $4.0 \times 10^{-3} \mathrm{m} .$ Exclud- ing the arm, the mass of the gymnast is 63 kg. (a) What is the compressional strain of the humerus? (b) By how much is the humerus compressed?
