1. Determine the magnitude of the resultant force acting on the bracket and its direction measured counterclockwise from the positive a axis.

2. The plate is subjected to the two forces at A and B as shown. If θ = 60°, determine the magnitude of the resultant of these two forces and its direction measured clockwise from the horizontal.

3. Resolve F1 into compenents along the u and v axes and determine the mangnitudes of these components.

4. Determine the magnitude and direction measured counterclockwise from the positive x axis of the resultant force of the three forces acting on the ring A. Take F1 = 500 N and O.= 20°.

5. a If 0 = 45°, determine the moment produced by the 4-kN force about point A.

6. The member is subjected to a force of 17 = 6 kN. If 0 = 45°, determine the moment produced by F about point A.
