1. If u = 30° and T = 6 kN, determine the magnitude of the resultant force acting on the
eyebolt and its direction measured clockwise from the positive x axis.
2. If FB = 2 kN and the resultant force acts along the positive u axis, determine the magnitude
of the resultant force and the angle u.
3. Determine the magnitude of the resultant force acting on the pin and its direction measured
clockwise from the positive x axis.

4. Determine the magnitude of the resultant force and its direction measured counter
clockwise from the positive x axis.
5. Determine the magnitude and direction measured counter clockwise from the positive x
axis of the resultant force acting on the ring at O if FA = 750 N and u = 45°.
6. The three concurrent forces acting on the screw eye produce a resultant force FR = 0. If F2
= 2/3 F1 and F1 is to be 90° from F2 as shown, determine the required magnitude of F3
expressed in terms of F1 and the angle u.
