The body of the chicken is supported from above by the hips and acts as a pendulum between the hips. Therefore, the chicken is stable for front-to-back displacements as well as for side-to-side displacements. Figure 9. The center of gravity of a chicken is below the hip joints. The chicken is in stable equilibrium.
62. 9.3 Stability. State the types of equilibrium. Describe stable and unstable equilibriums. Describe neutral equilibrium. It is one thing to have a system in equilibrium; it is quite another for it to be stable. The toy doll perched on the man’s hand in Figure 1, for example, is not in stable equilibrium. There are three types of ...
a state of equilibrium that is independent of a system’s displacements from its original position. stable equilibrium. a system, when displaced, experiences a net force or torque in a direction opposite to the direction of the displacement. unstable equilibrium.

Stability of an equilibrium can be determined by the second derivative of the potential. Defining a center of mass allows a simple way to study the behavior of a system or object as a whole. Stable equilibrium requires a restoring force. This restoring force can be derived by a Taylor expansion of the force, F (x).
neutral equilibrium: a state of equilibrium that is independent of a system’s displacements from its original position. stable equilibrium: a system, when displaced, experiences a net force or torque in a direction opposite to the direction of the displacement.

As a general introduction, Lagrangian mechanics is a formulation of classical mechanics that is based on the principle of stationary action and in which energies are used to describe motion. The equations of motion are then obtained by the Euler-Lagrange equation, which is the condition for the action being stationary.
