The quarter-circular slotted arm OA is rotating about a horizontal axis through point O with a constant counterclockwise angular velocity Ω = 9.9 rad /sec. The 0.11-lb particle P is epoxied to the arm at the position β = 64°. Determine the magnitude of the tangential force F parallel to the slot which the epoxy must support so that the particle does not move along the slot. The value of R = 1.4 ft.
