$1.$ Using the top table Provided in the image attached. $($figure $3-21$a$),$ design a fourbar linkage to produce a Class I coupler curve where the common link ratio is $2\mathrm{.}0$ and the Coupler angle is $288$ deg. $($a$)$ Variation of coupler curve shape with common link ratio and coupler angle

for a ground link ratio $\frac{L_1}{L_2}=2\mathrm{.}0$ Draw the linkage with the crank collinear extended with the ground link. Now, redraw the linkage by hand lightly $($or dashed$)$ for many unique crank positions $($perhaps every $30$ degrees$)$ paying special attention to the resulting coupler point locations. Connect the dots of the coupler point locations to create the coupler curve.
