1. Determine the magnitude and direction of the resultant force.
2. Determine the magnitude of the component force F and the magnitude of the resultant force F R if FR is directed along the
positive y axis.
3. Determine the magnitude of the resultant force and its direction, measured counterclockwise from the positive x axis.
4. A 30 kN force acts on the end of the 3 m lever as shown. Determine the moment of the force about O.
5. A 20 kN force is applied to the control rod AB as shown. Knowing that the length of the rod is 9 m. and that α = 25°,
determine the moment of the force about point B.
6. A 200 N force acts on the bracket shown below. Determine the moment of the force about point A.
7. Replace the three forces acting on the shaft beam by a single resultant force. Specify where the force acts, measured from
end A.
8. The overhanging beam is supported by a pin at A and the two-force strut BC. Determine the horizontal and vertical
components of reaction at A and the reaction at B on the beam.
