Gyroscopes Work

AI Thread Summary

Gyroscopes resist changes in their orientation due to the principle of conservation of angular momentum, which states that a rotating body will maintain its axis of rotation unless acted upon by an external force. This resistance to rotation in a different direction is a result of the gyroscopic effect, where the angular momentum vector remains constant. The stability of gyroscopes is also linked to their rotational speed; faster spinning gyroscopes exhibit greater stability and resistance to tipping. Additionally, gyroscopes do not fall over due to the torque generated by gravitational forces acting on their mass, which is countered by the gyroscopic effect. Understanding these principles is essential for grasping how gyroscopes maintain their upright position and resist unwanted rotation.

As the title says, I'm wondering how/why gyroscopes work. Why do they resist being rotated in a direction other than the direction in which they're already being rotated, and why don't they fall down?

I'm not the one to give a detailed explanation, but as a starter you should investigate conservation of angular momentum.

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
