A person with mass mp - 70 kg stands on a spinning platform disk with a radius of R = 2.1 m and mass mg 187 kg. The disk is initially spinning at a 2 rad/s. The person then walks 2/3 of the way toward the center of the disk (ending 0.7 m from the center). 1) What is the total moment of inertia of the system about the center of the disk when...

A person with mass mp = 74 kg stands on a spinning
platform disk with a radius of R = 2.37 m and mass md =
184 kg. The disk is initially spinning at ? = 1.9 rad/s. The person
then walks 2/3 of the way toward the center of the disk (ending
0.79 m from the center).

How much does the femur shorten when a 70-kg person stands on one foot? Assume that in the absence of stress, the femur has a length of 0.5 m. The femur’s cross-sectional area can be modeled as a hollow circular tube with internal diameter d1 = 2.5 cm and external diameter d2 = 3.3 cm. Young’s modulus for bone compression is 9 × 109 N/m2.
