A general fourbar linkage configuration and its notation are shown in Figure P6-1. The link lengths, coupler point location, and the values of θ2 and ω2 for the same fourbarlinkages as used for position analysis in Chapter 4 are redefined in Table P6-1, which is basically the same as Table P4-1. For the row(s) assigned, draw the linkage to scale and find the velocities of the pin joints A and B and of instant centers I1,3 and I2,4 using a graphical method. Then calculate ω3 and ω4 and find the velocity of point P.
