Objective: Experimental investigation of the vector addition of forces
The vector addition of forces can be demonstrated in a clear and simple manner on the force table. The point of action of three individual forces in equilibrium is exactly in the middle of the table. Determine the magnitude of the individual forces from the suspended weights and, using a protractor, note the angle of each force vector (the direction of each force). The result of the experiment can be evaluated analytically or represented as a graph.
