Free Body Diagram

The system of forces acting on a body tends to either rotate it or make the body undergo motion. In general, when an external agent exerts a force on a body, the body undergoes translational motion and rotational motion. The body has six degrees of freedom under the influence of that force. Here, three degrees of freedom are from the translational motion while the other three are from the rotation motion. However, sometimes the bodies are not allowed to undergo any motion and are fixed, under such conditions the body is said to be constrained.

P.1)
The rigid rod of length L is free to
rotate in a horizontal plane. A moment Mk is applied to
the vertical shaft that connects to the rod at O. What are
the reaction forces acting at O in terms of é, the rod's
angular speed, M, m, the mass of the rod, and L?
