All kinematic pairs are divided into classes (5 classes) depending on the
number of constraint conditions
.
Cylinder - plane (Fig. II.9).
RRTT Н = 4 S = 6 – Н = 2.
This is a second class kinematic pair of higher
degree P
2
.
The legend is
Prism - plane (Fig. II.10).
RTT Н = 3 S = 6 – Н = 3.
This is a third class kinematic pair P
3
(lower).
The legend is
Cylindrical KP
(Fig. II.11).
RT Н= 2 S= 4.
This is the fourth class kinematic pair P
