The acausal bond graph of system TwoLinkxyc is
displayed in Figure 8.1 (on page ) and its label
file is listed in Section 8.1.1 (on page ).
The subsystems are listed in Section 8.1.2 (on page ).
This system is identical to twolink except that the two
colocated SS components act at the tip in the and
directions instead of at the two joints.
It uses two compound components: ROD and GRAV. ROD
is essentially as described in Figure 10.2 of "Metamodelling" and GRAV represents gravity by a vertical acceleration as in Section
10.9 of "Metamodelling"
