Question:

Angular Momentum-Chair and Gyroscope?

We conducted this experiment: You will now conduct a tactile demonstration of angular momentum conservation by holding a spinning gyroscope while sitting in a swivel chair (see Figures 5 and 6) and then flipping the gyroscope over so that the direction of￿L is reversed.If we were to increase the gyroscope rotor’s mass but spin it up to the same initial speed, how would this affect the motion of the chair when the gyroscope is flipped? Why?Thank you!!!

Answer:

You have to conserve angluar momentum in this case so when you flip the gyroscope, the chair begins to turn in such a way that the sum of the angular momentum of the chari + gyroscope = angular momentum of gyroscope before it was flipped. If you increase rotor mass, you increase anglur momentum - they are linearly related so increase the mass by 10% will increase the angular momentum by 10% assuming the same rotor speed. If you increase the mass andthen repreat the experiment, you'll find the chair will turn faster than in th eprevious trial due to the increase in angular momentum.

check out what wikipedia has to furnish on Euler Angles. It has to do with 3-dimensional Dynamics. you will no longer run into something this difficult till around your' third 3 hundred and sixty 5 days at a substantial college in degree plans jointly with Aerospace Engineering or Physics. in case you have a particular undertaking regarding a gyroscope, or a three-dimensional undertaking, submit it, and that i will provide it a try. in actuality, the rotation motives a restoring rigidity, that retains the gyroscope interior the comparable airplane.

inspect what wikipedia has to grant on Euler Angles. It has to do with 3-dimensional Dynamics. you will no longer run into something this difficult until around your' third 365 days at a substantial college in degree plans which includes Aerospace Engineering or Physics. in case you have a particular concern concerning a gyroscope, or a three-dimensional concern, placed up it, and that i'll supply it a attempt. basically, the rotation reasons a restoring tension, that keeps the gyroscope interior a similar airplane.
