Figure 2.5 – Structural diagram of the mechanism
with one degree of mobility and two output links
We determine the number of links and kinematic pairs of a structural group
by formula (2.15):
Thus, the structural group consists of two links of one pair of the third
class, one pair of the fourth class and one pair of the fifth class.
The number of closed circuits formed by a structural group:
K = 3 – 2 = 1.
The number of redundant circuits links, of attached structural group:
S = 3 – (5 – 3) 1 – (5 – 4) 1 = 0.
In Fig. 2.5 the attached structural group is represented by a dashed line.
