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 0.26-m-long cylinder with an outer radius of 1.06 x 102 m and a hollow inner core with a radius of 3.6 x 10-³ m. Excluding the arm, the mass of the gymnast is 57 kg. Bone has a compressional Young's modulus of 9.4 x 10° N/m². (a) What is the compressional strain of the humerus? (b) By how much is the humerus compressed? Humerus out

Thank you for thoroughly explaining the concepts of how to work these practice problems out. 

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 0.26-m-long cylinder with an outer radius of 1.06 x 10-2 m and a hollow inner core with a radius of 3.6 x 10-³ m.
Excluding the arm, the mass of the gymnast is 57 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?
