Figure 8: Two pictures of a nonspinning Tedco gyroscope. We dene the 'top' to be the metal ball closest to the plastic gear wheel. In this section. you will use the Tedco Precision gyroscope to study what happens to i: when the net external torque i' 7E 0. We won't try to measure L, so this is a qualitative study. 1. Hold the top of the Tedco gyroscope, and make sure the rotor is not spinnine. Place it on the stand, at an angle. as shown in Fig. I. Get ready to catch it, let go of its top, and observe that the Tedco falls into a soft hand.

Show that the direction of i' is consistent with the way that the Tedco gyroscope falls (Hint: It started with E = 0, but falling increases E, about the contact point between the Tedco gyroscope and the stand. Use the right hand rule to check on the nal direction of E, after the Tedco starts falling)
