amistre64 · Answer

from what I can tell, moment refers to momentum.  An example I can think of is a teeter-totter.

Moment of inertia is dependent on the axis around which you are calculating it. It's part of the physics of rotating bodies. If you want to understand this physics overall, I recommend watching the three lectures beginning here: http://ocw.mit.edu/courses/physics/8-01-physics-i-classical-mechanics-fall-1999/video-lectures/lecture-19/

i saw the video

aravindg · Answer

but no problems explaned in it :(

jamesj · Answer

On the contrary, he gives three examples of moment of inertia in the first 9 minutes: disc, sphere, rod.

oh not that u see i need a problem using F.sin theta

jamesj · Answer

So you need to specify your problem much more precisely.  I don't know what you're asking.

k can u come to twiddla?

james pls

jamesj · Answer

I don't know what twiddla is.  In any case, figure out your question.

And as you know, I've asked you to show the working to a problem (the circle/triangle problem) so I know I'm not wasting time helping you.  But I'm yet to see anything for that or any other problem.
