Calculate the mobility of the human arm (from the shoulder to end of the wrist) using Gruebler's Mobility Equation.

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 65 kg. 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...
