Right hand rule for Spinning things...
Hi, I'm havign a hard time figuring out how the right hand rule works for Angular momentum, Angular velocity and torques.
Its so confusing because At university we get problems about rotating solid bodys like a disk on a rod, and when the question specifies the wheel direction as Clockwise and or anti clockwise, spinning on a horizontal axis.
I am not sure from WHICH point of view is the axis clock or anti clockwise.
When you look at a spinning object, being clock or anti clock depends on which side you look at it from...
Which also comes to my next confusing dilema.
If the direction of clock or anti clock depends on which side the obserevr views then using the right hand rule, doesn't that give 2 completely different sets of answers for angular velocity, anuglar momentum and torque?
Am i confusing anyone yet?
Can someone pelase explain to me how i should apply the right hand rule to find vector direction of velocity, anuglar momentum and torques!
Thanks
