Unformatted text preview: I = MR ^2 2 I = 25043.9 g cm^2 This is close to the experimental value of I. V2: Rotational Inertia of a rod In this experiment a larger falling mass (30.9 grams = Mt’) was suspended from the same apparatus, now with the rod cylinder of 630 grams, and 12.5 x 2.5 cm, from the same height 90 cm. Using the relationship: (see attached data sheet for t values). aR = 2h t^2 aR = 1.43 cm/s^2 Using this value of acceleration, and the relationship: I = m’gr^2 _ Io aR 31299.2 - 24305.6 = 6993.6 g cm^2 Using the equation: Ic = Mr (b^2 + l^2) 12 Ic = 6890.63 g cm^2 This is close to the experimental value, therefore the results are representative of good data collection.
