Question $-7$: Find the angular velocity of $BC,$ velocity of $C$ and velocity of point $E$ on $BC$ using

instant center method. The link $AB$ revolves with angular velocity of $ra\frac{d}{s}.$

Given

$AB=0\mathrm{.}7m$

$BC=1\mathrm{.}5m$

$CD=1\mathrm{.}25m$

$DA=2\mathrm{.}5m$

$BE=0\mathrm{.}75m$
