The tangential force F shown in figure below is applied to a disc is allowed to rotate about an axis through its center. The diameter of the disc is 24.0 cm. The magnitude of this tangential force is given in the graph of F vs. Angular Position. With the disc at rest initially and ignoring frictional torque, the disc's angular velocity after one full rotation is -31.4 rad/sec. What is the moment of inertia of the disk? 2.40 × 10-1...

A 60 kg gymnast leaves the floor to perform a somersault, with a reactive force of 2760 N. The center of gravity is 22 cm perpendicular from the line of action of the force. As she first leaves the floor, she can be modelled as a long cylinder with moment of inertia md^2/12 (where d is her length, 1.60 m). The time it takes her to leave the floor is 55 ms. As she leaves the floor calculate: 1. Torque...
