as long as the inverse matrix of exists. Using preassigned force densities to derive the linear equations with respect to nodal coordinates is the basic idea of force density method.

In Example 5.1, we demonstrate how the force density method works for form-finding of cable-nets, which carry only tension (positive force densities) in their members. Moreover, in the examples in this chapter, the units will be omitted without doing any harm to discussions on self-equilibrium as well as stability of the structures.

Form-finding of the cable-net as shown in Fig. 5.1 by using force density method.
