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. Procedure
