110 The Bennett linkage
Obviously, α, θ 1e , θ 2e, θ 1f and θ 2f from Eqs (5.80), (5.84) and (5.88) satisfy
Eq. (5.62).
Eqs (5.80), (5.89) and (5.90) relate the geometric parameters of an
alternative form of Bennett linkage to the design parameters, based on
which a model consisting of four square cross- section rods can be
installed together as shown in Figure 5.15. The linkage has mobility one
and can be folded into a compact bundle and deployed into a rhombus.
In practice, it is not necessary to know the characteristics of the original
Bennett linkage l, α, and extended distance on the axes of joints c (or d).
