A metal bar is in the xy-plane with one end of the bar at the origin. A force F =(9.00 N) î+(5.00 N) ĵ is applied to the bar at the point x = 3.00m, y = 4.00m. (a) In terms of unit vectors î and ĵ, what is the position vector r* for the point where the force is applied? (b) What are the magnitude and direction of the torque with respect to the origin produced by F?

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.
