I. INTRODUCTION
A. Background The forces that are involve with the experiments are basically focused on the concurrent forces. The experiment also allows us to develop the condition of balancing or arranging the angles both sides on a force table. This laboratory experiment allows us to take the mathematical abstraction of a vector to make it tangible as possible. This experiment will look into two ways of

II. METHODOLGY

A. Materials

ME-9447 Force Table, 3 pulleys and pulley clamps, 3 mass hangers, mass set, string, metric ruler, protractor, 2 sheets of paper.

B. Procedure

Experimental Method

As a result of trail and error method we find the angle for the third pulley and the mass that should had be suspended from it. This will balance the forces deployed on the strings due to the other two masses. While the third force is defined as the equilibrant (������⃗������) Since it is the force that establishes the equilibrium. It is also the negative of the resultant -������⃗������ = ������⃗������ = ������⃗ ������ + ������⃗������. We gathered and recorded the mass and the angle required for the third pulley to enable to put the system into the equilibrium in table 1.

To enable to determine the system is in equilibrium we use the following specifications.

Ring Method of Finding Equilibrium

For this method the ring should be centered over the post when the system is in equilibrium. So we tack the center post down so it will flush with the top surface of the force table and it will be no longer comptent to hold the ring in the position. We also pulled the ring slightly to the one side and release it to enable to inspect that the ring returns to the center. Then if not, adjust the mass or/and the angle of the pulley until the ring constantly returns to the center when it is pulled slightly to one side.

Anchor String Method of Finding
