- A system is said to be in stable equilibrium if, when displaced from equilibrium, it experiences a net force or torque in a direction opposite to the direction of the displacement. For example, a marble at the bottom of a bowl will experience a restoring force when displaced from its equilibrium position.

A system is in unstable equilibrium if, when displaced from equilibrium, it experiences a net force or torque in the same direction as the displacement from equilibrium. A system is in neutral equilibrium if its equilibrium is independent of displacements from its original position.

4 days ago · Eigenvalues can be used to determine whether a fixed point (also known as an equilibrium point) is stable or unstable. A stable fixed point is such that a system can be initially disturbed around its fixed point yet eventually return to its original location and remain there.

Jan 26, 2022 · In order to explore the stability of such fixed points, let us analyze the dynamics of small deviations ˜q(t) ≡ q(t) − qn from the equilibrium. For that, let us expand the function Uef (q) in the Taylor series at a fixed point: Uef(q) = Uef(qn) + dUef dq (qn)˜q + 1 2 d2Uef dq2 (qn)˜q2 + …. The first term on the right-hand side, Uef (qn ...
Equilibrium requires that the coefficients of ΔS and ΔV both vanish, that T = (∂E ∂S) ∗ V, N = T ∗ 0 and p = − (∂E ∂V) ∗ S, N = p ∗ 0 . The condition for stability is that ΔG> 0 for all (ΔS, ΔV). Stability therefore requires that the Hessian matrix Q be positive definite, with. Q = (∂2E ∂S2 ∂2E ∂S∂V ∂2E ∂S ...
