Introduction : In this experiment we used a force table to measure weight and balance out unknown masses and forces. The object was to find the point of equilibrium of the three masses at different angles by using a level force table and three hanging masses. Data analysis : In part A, we used the force table and set angles and masses to find the mass of the third unknown weight. We hung the two known masses at their angles and adjusted the masses until the system went into equilibrium and the ring was in the center of the table. In part B, we used both the graphical method and the analytical method to find the resultant of the forces. For the graphical method, we drew a scale diagram in which the lengths of the vectors were proportional to the magnitude of the forces. This gave us our third unknown force. With analytical we separated the force vectors into their X and Y components and found the resultant vector by using simple algebra and trig functions.

### 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.
