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-m-long cylinder with an outer radius of 1.00 × 10-2 m and a hollow inner core with a radius of 4.0 × 10-3 m. Excluding the arm, the mass of the gymnast is 6× kg.
(a) What is the compressional strain of the humerus?
(b) By how much is the humerus compressed?
