How to solve

RodOA rotates counterclockwise at a constant angular

rate ${}^{}=4ra\frac{d}{s}.$ The double collar $B$ is pin connected

together such that one collar slides over the rotating rod

and the other collar slides over the circular rod described

by the equation $r=(1\mathrm{.}6cos)m$ as shown in

$($Figure $1).$ Both collars have a mass of $0\mathrm{.}75$ kg $.$ Motion is

in the horizontal plane.

Determine the force which the circular rod exerts on one of the collars at the instant $=45.$

Express your answer to three significant figures and include the appropriate units.

Part B

Determine the force that $OA$ exerts on the other collar at the instant $=45.$

Express your answer to three significant figures and include the appropriate units.

$F_{OA}=0N$
