Solve on a paper showing all steps with numbers please A four bar mechanism has angular velocity of $10$ra$($d$)/($s$)$ccw and link lengths: Link $1$

$($ground$)=6,$ Link $2($crank$)=2,$ Link $3($coupler$)=7,$ and Link $4($rocker$)=9$

units. using the instant center approach find the angular speed for link $4$ directly

using I$\_(24)$ at the extreme crank positions. Make clear sketch for each of the two

extreme positions.
