Kirchhoff’s circulation law has previously been adapted for studies of underconstraint.
Here Kirchhoff’s cutset law is also adapted for studies of overconstraint. The two
procedures are presented in tandem to emphasise their duality. The same tasks are then undertaken
using dual virtual power methods. One is a new procedure for underconstraint that introduces
the concepts of cutset motion and virtual action, dual with previously reported circuit
action and virtual motion. Of the four methods described, the superior ones for each task are
