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.

(unknown) tension in string 2, because the line of action of T goes through the point of attachment of string 2, and the lever arm of the fo
case would be zero. Eliminating terms from the torque equation, particularly those involving unknown quantities, generally makes it easier

Learning Goal:
To practice Problem-Solving Strategy 11.1 Equilibrium of a Rigid
Body.
A horizontal uniform bar of mass 3 kg and length 3.0 m is hung
horizontally on two vertical strings. String 1 is attached to the end
of the bar, and string 2 is attached a distance 0.7 m from the
other end. A monkey of mass 1.5 kg walks from one end of the
bar to the other. Find the tension T in string 1 at the moment
that the monkey is haltway between the ends of the bar
Now, choose a set of coordinate axes, and specify a positive direction of rotation for torques.
EXECUTE the solution as follows
• Part C
Find T, the magnitude of the force of tension in string 1, at the moment that the monkey is halfway between the ends of the bar.
Express your answer in newtons using three significant figures.
