Anh Le PHY-1053 Professor McNutt Lab 3 Report: Force Table Lab Introduction In this experiment, we used a round table with a center pin and angle divisions marked around its outside edge. A ring is placed around the center pin that has strings attached to it. Those strings are run over pulleys at different locations around the table and various masses are hung from their ends. The purpose of this experiment is to verify vector addition. Theory: According to Newton’s second law, an object that is not accelerating must have no net force. Therefore, the sum of the vectors of the forces on that object must be zero. The method for vector addition includes finding the orthogonal components of each vector and adding so that the components of the resultant vector T 12 is related to the components of the individual Vectors T 1 , T 2 , etc., in the following way: T t,x = T 1x + T 2x T t,y = T 1y + T 2y The magnitude of the resultant vector is = , + , T12 Tt x2 Tt y2 The equilibrant vector is the vector T 3 which when added to T 12 returns zero.
