Find the angular momentum of a disc about the axis shown in figure in the following situations.

A uniform rod of mass m and length L is fixed to an axis, making an angle theta with it as shown in the figure. The rod is rotated about this axis so that the free end of the rod moves with a uniform speed ‘v’. Find the angular momentum of the rod about the axis. Is the angular momentum of the rod about point A constant?

A disc of mass m and radius R moves in the x-y plane as shown in Fig. The angular momentum of the disc about the origin O at the instant shown is
