PROBLEMS FOR RESOLUTION AND COMPOSITION

$2.$ For the offset slider$-$crank mechanism shown. $C_{2}A=3\mathrm{.}5cm$;$AB=11cm$;$AD=15\mathrm{.}5cm.$ crank $2$ is at $45$ with the horizontal, and $C_2$ is $2$ cm above the path of Block $4.$ If ${}_2=300ra\frac{d}{m}in,$ clock$-$wise, determine the velocity of pin D and block $4,$ as well as the magnitude and the sense of the angular velocity of link $3.$ Use $k_s=1$:$1,k_v=300c\frac{m}{m}in.$
