If necessary, explain why your predictions were incorrect. (d) use these results to describe what should happen if you pull the string at various angles. Explain what happens when you pull the string at that angle, and explain why: your ta has a gyroscope and a string. You can use the string to set they gyroscope spinning very quickly. When you get the hang of that, try the following two things: (a) hold one end of the frame with just two ngers and a thumb while the gyroscope is spinning fast. Hold it upright, then quickly try to ip it 180 . Describe what you feel. (b) when the gyroscope is spinning fast it is very stable.
