A $0\mathrm{.}3-$kg particle $P$ is constrained to move along the vertical$-$plane circular slot of radius $r=1\mathrm{.}1m$ and is confined to the slot of arm $OA,$

which rotates about a horizontal axis through $O$ with a constant angular rate $=2\mathrm{.}8ra\frac{d}{s}.$ For the instant when $=23,$ determine the

magnitue of the force $N$ exerted on the particle by the circular constraint and the magnitude of the force $R$ exerted on it by the slotted

arm.

Answers:
