   This is the definition of the equilibrium state of a material in the absence of any fields acting on the material, such as gravity. When such fields exist they have to be taken into account in the determination of the equilibrium state.

   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.

   How do you know if a system is stable?

   • 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.

   What is an example of stable equilibrium?

   • For example, a marble at the bottom of a bowl will experience a restoring force when displaced from its equilibrium position. This force moves it back toward the equilibrium position. Most systems are in stable equilibrium, especially for small displacements. For another example of stable equilibrium, see the pencil in Figure 9.3.2 9.3. 2.

   How do you know if a system is in stable equilibrium?

   • 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 the direction of the displacement. 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.

   What makes a building a stable equilibrium?

   • Engineers and architects strive to achieve extremely stable equilibriums for buildings and other systems that must withstand wind, earthquakes, and other forces that displace them from equilibrium. Although the examples in this section emphasize gravitational forces, the basic conditions for equilibrium are the same for all types of forces.

   Is a system in equilibrium a stable system?

   • 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 9.3.1 9.3. 1, for example, is not in stable equilibrium. There are three types of equilibrium: stable, unstable, and neutral. Figures throughout this module illustrate various examples.

   Is a material unstable or metastable?

   • Most materials are unstable or metastable. A material is in a metastable state if its energy is at a local minimum, but not the lowest energy state. A corrie lake is a metastable location of water. Water in the lake attains its lowest energy when it reaches the sea.

   Jul 26, 2015 · The concept of stability is a central one in science but the term is utilized in two quite different ways. Following the establishment of thermodynamics as a quantitative discipline, the term can be used in an energy/entropy sense. Thus a system of lower enthalpy and/or higher entropy is considered more stable.
