Restricting movement of a gyroscope, stabilizing gyros |
| Question: |
I'm building a self-balancing bike(while its standing at rest) for my physics project. I have a few questions. First of all, is the gyro effect negated when a gyroscope is restricted in the dimension it is supposed to spin to? as in, if the gyro wheel is fixed to the bike by an axle, spinning in a vertical plane, so that when the bike leans, the gyro wheel can't turn, will the effect be completely negated? also, as far as i understand, stabilizing gyroscopes are in a horizontal plane, are fixed from side-to-side movement (so that they are actually able to exert a force on the object they are stabilizing), but are allowed to pivot forward and back. In this case, when the bike leans to one side for long enough, wouldnt the gyroscope eventually become too vertical to prevent it from falling over? is that a natural limitation of stabilizing gyroscopes, and they can only slow down the process of falling, not prevent it? |

| | | I can't give you a complete answer but I can tell you if a gyroscope isn't allowed to precess, it's righting effect is definitely reduced if not completely eliminated. Notice gyros tend to be used more for detection of attitude rather than control of attitude. Also notice if you stop a toy gyroscope from precessing it immediately falls. If you allowed the gyro to precess independent of the bike, when it's axis was aligned back to front your bike would fall. I'm not sure if there is a way to make it work with multiple gyroscopes.

| | | A gyro is a gyro is a gyro. If you restrict its movement ability, it still wants to become level. Think of it this way: If you take a book and lock the book up so no one can read it, it is still a book, isn't it?
