Problem $12\mathrm{.}070-$ A mechanism with a rotating arm and a circular slot

Pin $B$ weighs $4$ oz and is free to slide in a horizontal plane along the rotating arm $OC$ and along the circular slot $DE$ of

radius $b=22in.$ Neglect friction and assume that ${}^{}=15ra\frac{d}{s}$ and ${}^{}=250ra\frac{d}{s^2}$ for a position $=20.$

Problem $12\mathrm{.}070.$a $-$ Resultant force exerted on the pin

Determine for that position, the radial and transverse components of the resultant force exerted on pin $B.$

The radial component of the resultant force is $-$

Ib and the transverse component is

lb $.$
