Problem $2(10$ points$)$

A four$-$bar linkage is given with four pin joint locations in $2D$ space specified as points $A_0,A,B,$

and $B_0($where $A_{0}A$ is the input link $L_2,AB$ is the coupler link $L_3,B_{0}B$ is the output link $L_4,$ and

$A_0{B}_0$ is ground link $L_1).$ Each point has an $x$ and $y$ coordinate.

Create a MATLAB program to plot and classify a four$-$bar linkage as Class $1,2,$ or $3$ by checking if

Grashoff's criterion is satisfied. If Class $1,$ specify the type as a crank$-$rocker, rocker$-$crank,

special case of double$-$rocker, or double$-$crank. Please note that a code was constructed in the

videos in Module $2.$

Please submit both, a plot of the linkage and its classification for each of the following

linkages. Program may be submitted in an appendix. Points are given in $x$;$y$ format.

Add any supporting work in the appendix. $**$PLEASE CREATE A MATLAB PROGRAM$**$
