4. The rectangular framework is subjected to the following non-concurrent system of forces: a 30lb- force below the origin, a 20lb-force 3ft above the origin and making an angle of 30° N of E, a 100lb-force with a horizontal distance of 3ft and a vertical distance of 4ft from the origin and making an angle of 45° NW, a 60lb-force with the same distance like the previous force but along the positive x-axis, and a 100lb- force 4ft to the right of the origin and making an angle of 60° S of W. Determine the magnitude and direction of the resultant, as well as its moment arm relative to the origin.

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.
