Question

In the demonstration of Bicycle wheel gyroscope procession. Tthe slow, horizontal rotation of a spinning bicycle wheel with its axis oriented horizontally is called "precession," and we can talk about "rate of precession," in terms of how quickly the bicycle wheel rotates horizontally .Make a prediction and explain your prediction: if you spun up the bicycle wheel to spin faster before you let go of one end, will the bicycle wheel precess faster or slower? (Or, another way to answer the same question is, if you spun up the bicycle wheel to spin slower before you let go of one end, will the bicycle wheel precess slower or faster?)

Answer 1

The answer is described below:

The angular speed of precession of the bicycle wheel is inversely proportional to the angular speed of rotation of the bicycle. In other words, when an end is held on the axis of rotation of the wheel, the angular speed of the wheel increases, therefore the precession is slower and in the end it will fall

One way to increase the precession is to release the other end of the axis of rotation of the wheel, so that the angular speed decreases and thus the wheel rotates in a horizontal plane. In this way we can perform an angular momentum, product of the torque executed by the weight of the bicycle wheel.
