Why is angular momentum conserved here?

[QUOTE="PeroK, post: 6321269, member: 493650"] AM is always calculated about a point. In this case, the AM in that equation is taken about a point on the surface. As the force acts in the direction of the surface, the AM about that point is conserved. You can also solve this problem using AM about the initial position of the centre of the cylinder. In that case, the final AM is different from the initial AM because of the external torque about that point. In general, if you have an external force, then the AM about a point on the line of that force is conserved. [/QUOTE]
