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.
