Forces in Equilibrium, Force Table
Procedure Part 1
Angles are to be expressed relative to a superimposed coordinate system, choosing the +X–axis to lie along the 0° direction of the force table.
4. Repeat for 200 g at 270° and masses of 200 g and 150 g.
5. Repeat for 250 g at 270° and masses of 150 g and 150 g.
6. You should have 3 different diagrams, one for each experiment, in your data book.
Procedure Part II
1. Calculate theoretically the resultant, angle and magnitude, if we hang masses of 100g, 150g and 200g at angles of 30°, 120° and 330°, respectively.
1. Add a fourth pulley to the Force Table and prove your results.
1. Determine the force (F = mg) applied to each string and the components of those forces.
2. Draw an accurate sketch of the force vectors on the appropriate coordinate system. Include the magnitude of the force and angles.
3. Construct a table listing the components Fx and Fy for each one of the forces.
Report Part I
4. Assuming that you only know the force applyed a 270° and the angles, calculate mathematically the other two forces.
5. Compare these two calculated forces with the ones determined experimentally.
6. For one of the experiments, show all of the intermediate calculations needed to obtain each of the x and y force components.
