A persons head is bent over her book. The head weighs P=37.2 N and is supported by the muscle force F m exerted by the neck extensor muscles and by the contact force F c exerted at the atlantooccipital joint. Given that the magnitude of F m is 60.0 N and is directed 35.0 degree below the horizontal. Find the magnitude of the contact force F c.
Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
Equilibrium of Forces
The tension created on one body during push or pull is known as force.

Introduction:
Physics plays a crucial role in day to day life. Every action in nature is the result of laws of physics. Physics is the language to understand the nature. Various forms of energy can convert into the most usable form. Work done by the human body results into the movements of the different body parts. The direction of each body part can be considered as a vector in the plane.
