Experiment 101
In this experiment, we determined the resultant and equilibrant of system of forces using the force table given and after gathering the data, we compared them with the different methods involved. The main material we used in this experiment is called force table. It has system of strings with varying tensions that act concurrently. It also has 4 pcs of super pulley with clamp and 4 pcs of mass hanger which weigh 5 grams each. There is a ring in the center of the force table that indicates if the forces are balance. We began the actual experiment by increasing differently the mass of each hanger using the slotted mass. Afterwards, we measured the angles of the strings by using trial and error in

We tried to fix our mistake and it was fine. We were able to fix our mistake and continue the experiment. We had fun in balancing the force table and computing for the resultant by using component method and polygon method. The experiment gave us a preparation on how to solve certain situation that may happen in our lives.


1. Why is it important for the ring to be at the center? Since the mass hangers have equal masses, can you disregard them in the experiment? Why?
- It is important for the ring to be at the center because it indicates if the forces are balance or not. You can’t disregard the ring in the experiment because it will affect the resulting value if you will compute for the resultant of the force.
2. When a pull is applied on the ring and then released, why does it sometimes fail to return to the center?
- Sometimes the forces are close to equilibrium but are not exactly equal so a slight disturbance in the balance will cause significant effect.
3. What is the significance of the resultant of F1, F2, and F3 to the remaining force F4? What generalization can you make regarding their relationships?
- It will act as a force that will completely neutralize F4. The force F4 and the resultant of F1, F2, F3 are exactly opposite of each other.
4. If the order of adding vectors is changed (i.e. from F1 + F2 + F3 to F2 + F1 + F3) will the resultant be different? Why?
- No, because
