Dylan Bloom Olivia Nixon Joe Durantini 3 October 2010 Lab 2: SHM Mass on Spring Introduction: This experiment was done to gain practice with finding spring constants via Hooke’s law and SMH oscillation theory. By measuring the displacement or period of oscillation of different masses attached to a hanging spring (or springs) we can use the following formulas to determine the spring constant k. Procedure : Part A First we measured the length of the spring so that we could determine the displacement, or change in length, for the following attached weights: 50, 100, 150, 200, 250, 300, 350, 400 g. We then graphed the measured displacement against the added mass and used the resulting equation of the line to calculate k. Part B First we measured the weight of the spring. Next, beginning at 100g and increasing at 50g increments, we measured the time for five oscillations of the spring and the added weight three times per weight, dividing by five and taking the average to determine period. Then we graphed the added mass versus period and period squared. Finally we
