7.2 Layouts for the Bennett linkage
7.2.1 Case I
A single Bennett linkage consisting of four links can be represented schema tically by a square as in Chapter 5. When it is used as a building block
inscribed by a square of identical orientation, tiling (4

) in Figure 7.1(b)
presents the simplest way to form an assembly in which other Bennett linkages are connected to each of its sides completing a layout shown in Figure
7.3(a).
The kinematics of the assembly can be examined by first considering
two adjacent Bennett linkages ABCD and DCEF, Figure 7.3. Without other
