The moment of inertia of the human body about an axis through
its center of mass is important in the application of biomechanics
to sports such as diving and gymnastics. We can measure the body's
moment of inertia in a particular position while a person remains
in that position on a horizontal turntable, with the bodys center
of mass on the turntable's rotational axis. The turntable with the
person on it is then accelerated from rest by a torque that...
