does anybody knows how to find the angular velocity of the midpoint of a bar??
I think you're going to have to provide additional information...
no,let say the angular velocity of a bar is given but what is the angular velocity of the midpoint of the bar itself
i would say that the midpoint has the same angular velocity.
A single point can't have angular velocity about itself, can it? (assuming the "midpoint" is also the pivot point)
I do believe that for a rigid body, the angulare velocity is the same for all points on the body.
But the center point is not moving, so it has no angular velocity. I guess it doen't really matter since the point has no mass.
I think that the axis, which runs through the point of rotation, will be rotating, although since r = o, it will have no tangential velocity.
actually, the center point is moving. it just happens to be spinning in the same place.
the centre point moves
A point can't "spin." A very, very small object can, but not a point.
this is a stupid argument :tongue2:
i thought id enter it, but... nah...
i agree... i think i'll stop now.
