Explanation:
The forces acting on the bead are
- the normal force
N exerted on it by the rod in the horizontal direction. - its weight
mg in the vertically downward direction - the force of sliding friction
mu N vertically upward.
The bead has acceleration components of
Thus, Newton's second law takes the form
This implies that
Hence
