I just need $7-4$ question using row a and by analythical method.

Thank you$**7-3$ The link lengths, coupler point location, and the values of ${}_2,{}_2,$ and ${}_2$ for the same

fourbar linkages as used for position and velocity analysis in Chapters $4$ and $6$ are

redefined in Table P$7-1($p$\mathrm{.}380),$ which is the same as Table P$6-1($p$\mathrm{.}328).$ The genera

linkage configuration and terminology are shown in Figure P$7-1($p$.380).$ For the

row$(s)$ assigned, draw the linkage to scale and graphically find the accelerations of

points A and $B.$ Then calculate ${}_3$ and ${}_4$ and the acceleration of point $P.$

$7-4$ Repeat problen $7-3,$ solving by the analytical vector loop method of Section $7\mathrm{.}3($p$.$

$.$

$$ Drawings of these linkages are in the PDF Problem Workbook folder on the DVD$.$
