A rigid rod resting on a fulcrum has the following 20-lbs forces acting on it. A is attached 2 feet from the left of the fulcrum acting vertical upward. B is 4 feet to the left of the fulcrum, acting downward at an angle of 30° with respect to the horizontal. C is 6 feet from the left of the fulcrum, acting upward with an angle of 45° with respect to the horizontal. D is attached 2 feet at the right of the fulcrum, acting downward at an angle of 60° respect to the horizontal. Where can a 20 lbs force be placed to put the system in equilibrium?

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.
