QUESTION $5$

The linkage shown is not drawn to scale. Crank OC rotated at $250rpm$ anticlockwise. Find the angular velocity of the link $CP$ and the right angle plate AEQ. Also determine the velocity of point $D$ and point $E.$ Use the scale of $1mm=4mm$ for the configuration diagram.

If a force of $300N$ is applied at point $D,200mm$ from $C$ in the direction shown, find the reactions at $C$ and $P.OC=AP=QE=127$;$CP=508$;$AQ=254mm$
