012-04715B Experiment 1: Vector Addition EQUIPMENT NEEDED: ME-9447 Force Table, –3 pulleys and pulley clamps, –3 mass hangers, –mass set, –string, – metric ruler, –protractor, –2 sheets of paper Purpose The purpose of this experiment is to use the force table to experimentally determine the force which balances two other forces. - Page 10 012-04715B Force Table θ Figure 5 Components Component Method Two forces are added together by adding the x- and y-components of the forces. First the two forces are broken into their x- and y-components using trigonometry: x + A y and B x + B where is the x-component of vector...
- Page 11 Force Table 012-04715B Setup ➀ Assemble the force table as shown in the Assembly section. Use three pulleys (two for the forces that will be added and one for the force that balances the sum of the two forces). ➁ If you are using the Ring Method, screw the center post up so that it will hold the ring in place when the masses are suspended from the two pulleys.
- Page 12 012-04715B Force Table Analysis To determine theoretically what mass should be suspended from the third pulley, and at what angle, calculate the magnitude and direction of the equilibrant ( ) by the component method and the graphical method. Component Method On a separate piece of paper, add the vector components of Force A and Force B to determine the magnitude of the equilibrant.

Force Table 012-04715B Appendix Storage The force table may be stored with or without the pulleys and pulley clips attached. To minimize the storage space needed for the force table, remove the legs by unscrewing them from the table. Then put the legs in the clips that are on the underside of the force table. -
