The humerus, which is the upper arm bone between the elbow and the shoulder joint, can be approximated as a 33 -cm-long hollow cylinder with outer radius 1.05 cm and inner radius 0.43 cm. Suppose a gymnast whose arm bone has these dimensions does a one-arm handstand. Excluding the arm, the mass of the gymnast is 66 kg. (calculators allowed)
(a) What is the compressional strain of the humerus? Use the value 1.4×1010 N/m2 for Young's modulus.
(b) By how much is the humerus compressed?

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 0.29-m-long cylinder with an outer radius of 1.20 x 10-2 m and a hollow inner core with a radius of 4.2 x 10-3 m. Excluding the arm, the mass of the gymnast is 68 kg. Bone has a compressional Young's modulus of 9.4 x 109 N/m2. (a) What is the compressional strain of the...
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 0.35-m-long cylinder with an outer radius of 1.09 x 102 m and a hollow inner core with a radius of 3.6 x 10 m. Excluding the arm, the mass of the gymnast is 47 kg. Bone has a compressional Young's modulus of 9.4 x 10' N/m2. (a) What is the compressional strain of the...
