You have it backwards. It is the angular momentum vector that points along the spindle. Consider an element of mass ##dm## on the... -
test123 replied to the thread What force causes precession?.Ok, I think I finally get it. Because L by definition is along the spindle, and we know L shifts because of torque, we know the spindle...

test123 replied to the thread What force causes precession?.First let me clarify, I completely understand the concepts of angular momentum and that its time derivative is torque. I completely...

test123 replied to the thread What force causes precession?.By the spindle I meant the axis of the top that passes through the little beam at the top. I know the top could theoretically rotate...
-
test123 replied to the thread What force causes precession?.I understand the whole L changing thing, and the T dt = dL thing. What I don't understand is why the spindle of the top has to be...

test123 replied to the thread What force causes precession?.The direction of the angular velocity would point at the next point in the precession. I understand that if the wheel rotated to the...

test123 replied to the thread What force causes precession?.I understand why L changes, I just don't understand why the wheel attempts to be flush with the plane of rotation. In other words, why...

test123 replied to the thread What force causes precession?.Here is my diagram, it doesn't let me edit my question anymore.

In class, the prof. gave the following explanation for why the wheel precesses: Whenever the wheel is spinning, it has a angular...
