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.

An 8.0m long uniform boom weighing 1200N is anchored to the ground at one end and sticks up at 35 degrees above the horizontal toward the right. It is held in this position by a horizontal cable at ratchet to the top of the beam and pulling left with tension T. If a 600N weight hangs from the top of this boom what is the tension in that cable. I would suggest using the bottom end of the boom as your pivot point for calculating the torques.
