Physics 123 – Minilab 3 FORCE VECTORS Introduction The purpose of this minilab is to practice working with vectors, both experimentally and theoretically. Force is represented by a vector. One of the conditions for a body to be in static equilibrium (not accelerating) is that the vector sum of all the forces acting on the body must be zero: Σ F = 0. In this minilab you will add several forces acting on a body using components to determine what additional force must be added to achieve equilibrium. You will then verify your calculation using a force table. A force table is a stand holding a circular board with degree markings around the outer rim. Three strings are tied to a ring at the center of the table; each string passes over a pulley clamped to the edge of the board with a mass holder attached to the hanging end. Masses placed in the holders create tensions (forces) in the strings attached to the ring. When the vector sum of these tensions is zero, the ring is in equilibrium and rests in a position concentric with the center of the force table.

### 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.
