Rotational Motion Part 1

A uniform rod of length 'l' is pivoted at one ofits ends on a vertical shaft of negligible radius.When the shaft rotates at angular speed ω therod makes an angle θ with it (see figure). Tofind θ equate the rate of change of angularmomentum (direction going into the paper )
