=== M-2: Equilibrium of Forces === <> ==== Objective ==== * The objective of this lab is to experimentally verify vector addition of forces ==== Equipment ==== * Circular Horizontal Force Table with 360-degree scale * 4 Orange Pulleys * 4 50g Weight Hangers * Slotted masses * Protractor * Rulers ==== Procedure ==== * Choose two concurrent forces, each between 100 and 500 gram weight and not in the same direction. Add these two vectors to find the resultant force * Use both a graphical construction and a numerical computation * Check your result by setting up the two original forces on the force table, and finding experimentally the single force which will hold them in equilibrium. * Random errors are due mainly to friction. You can estimate them by repeating the measurement several times. * Are your measured values consistent with the computation and graphical construction? * Repeat the experiment, but use three different original forces. ==== Post-Experiment Question ==== * If the weight hangers used all have identical masses, can their weight be neglected? ---- [[M-2-200 | M-2 Equipment]] [[201/207 Experiments]] [[Online Lab Manuals]] [[Online Lab Index]]
