Introduction The purpose of this experiment is to use the force table to experimentally determine the force which balances two other forces acting on the same object (knot). The result is checked by adding the two forces using the component method of adding the vectors. The Equilibrium force balances the Resultant force. The figure below shows the forces. -E = R R R = A +B In this experiment the resultant force R is found by adding the two vector forces Å and B using their component. Two forces are applied by hanging masses over pulleys positioned at certain angles. Then the angles and masses hung over a third pulley is adjusted until it balances the other two forces, and this third force is called the Equilibrant force, E, since it is the force which establishes equilibrium. The equilibrant force vector is not the same as the resultant force vector, E O R. The resultant force is the addition of the two forces. While the equilibrant force is equal in magnitude to the resultant force but in the opposite direction. Il = RI. because it balances the resultant. Therefore, equilibrant force vector is the negative of the resultant force vector._-E = R.
