Lab #7 Static Equilibrium Purpose: To investigate the two conditions of static equilibrium. Equipment: Force table, weight hangers and weight set Protractor Rectangular graph paper (2 sheets) Moment of Force Apparatus Principle(s): For Part 1 we were given a mass and position for two of three forces all attached to one ring in the middle of a circle. We experimentally found the weight and position of the third force by trial and error until the ring was centered in the middle of the table. For Part 2 we experimentally found the correct position of a set weight to balance a meter stick. We then checked our work be using the equation to find the correct position. Procedure: Part 1: On a force table we hung a mass of 100g at 30 degrees and a mass of 200g at 150 degrees. We experimentally found the weight and position of the third force by trial and error until the ring was centered in the middle of the table. Part 2: We balanced a meter stick with 2 given weights hanging on the left side and a variable on the other. First we found what position the variable weight at 30g had to be in to balance the meter stick. Then we moved the meter stick left 10 cm and repeated the process with a 40g
