PHYS211 Lab Experiment 2 Vector Addition Equipment: Force Table String Weight Hangers Protractor Ring Pulleys Massess 30-cm Ruler Procedure: Force Table 1. Position two pulleys at the assigned angles. These pulley positions must remain fixed during the experiment. 2. Place the ring over the central peg and run the support strings over the pulleys. 3. On each string that runs over these pulleys, place a mass of 200g (including hanger - each hanger has a mass of 50 g). 4. With a third pulley and masses, balance the forces exerted by the two 200 g masses. 5. To balance the forces, move the third pulley around to find the direction of the balancing force 6. Add masses to the third hanger until the ring is centered. 7. The balancing force obtained in (c) is the equilibrant force. The resultant has the same magnitude as the equilibrant. 8. To determine the direction of the resultant, subtract 180 degrees from the direction of the equilibrant.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
