Nodal Equilibrium Equations
To resolve this difficulty, first we make use of the nodal equilibrium equations in order to reduce the number of independent unknown member forces. The nodal equilibrium equation for the system has the form:
where
- : Vector of nodal forces at all N degrees of freedom of the system.
- : The resulting nodal equilibrium matrix
- : The vector of forces arising from loading on the members.
In the case of determinate systems, matrix b is square and the solution for Q can be found immediately from (3) provided that the system is stable.

Famous quotes containing the word equilibrium:
“When a person hasn’t in him that which is higher and stronger than all external influences, it is enough for him to catch a good cold in order to lose his equilibrium and begin to see an owl in every bird, to hear a dog’s bark in every sound.”
—Anton Pavlovich Chekhov (1860–1904)
