Lab 9: Rotational Motion Monday 6:20-8:10pm Abstract The objective of this lab is met, the values of I s and I d are different because of friction in the experiment. Also the result shows that the moment of inertia depends on the rotation axis for a given object.

Objective The objective of this lab is to see that the moment of inertia depends on the rotation axis for a given object and look at rotational motion from an energy viewpoint. Procedure There were two parts in this lab. First part, the block was mounted through its shortest axis onto the rotary encoder, then start the data acquisition and release the pulley to record the data. Part two, the block was mounted through its longest hole and repeat the same step as part one. Result Shortest axis: I s = 1.20*10 -4 ± 1.88*10 -7 kg*m 2 I d = 1.55*10 -4 ± 7.22*10 -6 kg*m 2 Percentage difference = 29.2% τ f = 5.97*10 -3 N*m Longest axis: I s = 7.38*10 -5 ± 2.59*10 -7 kg*m 2 I d = 9.75*10 -5 ± 4.54*10 -6 kg*m 2 Percentage difference = 32.1%
