$4.$ Given the inverted slider$-$crank mechanism shown in Figure $4,$ find the angular acceleration values

for links $3$ and $4$ and the linear acceleration vector for link $3$ relative to link $4.$ Link $1($from Ao to Bo$)$ is $6\mathrm{.}25$ m and at an angle of $172$ deg. Link $2$ is $1\mathrm{.}75$ m long and at an angle of $46$ deg. Link $3$ is $5\mathrm{.}70$ m from pin C to the top of the piston. Currently, the top of the piston, link $4,$ is $1\mathrm{.}72$ m from bearing Bo and at an angle of $3\mathrm{.}01$ deg. Link $2$ is travelling at a constant $\backslash (6\backslash$mathrm$\{$rad$\}/\backslash$mathrm$\{$s$\}\backslash )$ clockwise.
