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 P7-1 (p. 380), which is the same as Table P6-1 (p. 328). The general linkage configuration and terminology are shown in Figure P7-1 (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.
