    Mechanics - Angular momentum not about C.O.M. with translational motion

    Cool... Thanks very much for clearing that up for me... :smile:

    Mechanics - Angular momentum not about C.O.M. with translational motion

    Ahhh... I think my brain just was refusing to believe that you could use Izω when the angular velocity isn't around that point... Neat! :biggrin: I was trying to get around the by taking it from the point of view of a moving inertial frame so it would appear to that observer to be both...

    Mechanics - Angular momentum not about C.O.M. with translational motion

    Ah, OK, so it's basicly unnatural it say a body rotates about anywhere other than its centre of mass without having an axis of rotation... However, I'm still unsure how I would find the angular momentum about a point other than the axis of rotation (Taking the case that it is fixed and not...

    Mechanics - Angular momentum not about C.O.M. with translational motion

    Just to clarify, when I said the translational motion I meant a translational motion independent of the rotation. So for instance, the endpoint of the rod is also moving with velocity u, as well as being the axis for the rotation of the body... Just to make sure... :smile:

    Mechanics - Angular momentum not about C.O.M. with translational motion

    So when finding the angular momentum about the endpoint (centre of rotation) I can use the parallel axis theorem, but how can I now add the angular momentum for the translational motion? Adding the \mathbf{r}_{c.o.m.}\times m\mathbf{v}_{c.o.m.} component to it seems wrong as now the...

    Mechanics - Angular momentum not about C.O.M. with translational motion

    Thanks! :) Sorry for late response, I left the library early and don't have internet in my flat... (Like living in the dark ages here!) What I think I'm having difficulty understanding is if the body is rotating about an axis that isn't its centre of mass, for instance a uniform rod with...

    Mechanics - Angular momentum not about C.O.M. with translational motion

    Perhaps this should be under physics, but my mechanics course is done by the maths department... I don't actually have a particular problem, just a question. If you have a body (say a rod) with translational motion and rotation about an axis that is not its centre of mass, is there a way...
