  3. Statics - Wikipedia

    en.wikipedia.org/wiki/Statics

    The static equilibrium of a particle is an important concept in statics. A particle is in equilibrium only if the resultant of all forces acting on the particle is equal to zero. In a rectangular coordinate system the equilibrium equations can be represented by three scalar equations, where the sums of forces in all three directions are equal ...

  4. Guyan reduction - Wikipedia

    en.wikipedia.org/wiki/Guyan_reduction

    In computational mechanics, Guyan reduction, [1] also known as static condensation, is a dimensionality reduction method which reduces the number of degrees of freedom by ignoring the inertial terms of the equilibrium equations and expressing the unloaded degrees of freedom in terms of the loaded degrees of freedom.

    Static is a 2012 horror film directed by Todd Levin and starring Sara Paxton and Milo Ventimiglia. [1] [2] Plot. Jonathan Dade (Ventimiglia), a novelist, and his wife ...

  6. Virtual work - Wikipedia

    en.wikipedia.org/wiki/Virtual_work

    Static equilibrium is a state in which the net force and net torque acted upon the system is zero. In other words, both linear momentum and angular momentum of the system are conserved. The principle of virtual work states that the virtual work of the applied forces is zero for all virtual movements of the system from static equilibrium.

  7. Tolman–Oppenheimer–Volkoff equation - Wikipedia

    Let us assume a static, spherically symmetric perfect fluid. The metric components are similar to those for the Schwarzschild metric: [2] = = ⁡ By the perfect fluid assumption, the stress-energy tensor is diagonal (in the central spherical coordinate system), with eigenvalues of energy density and pressure:

  8. List of types of equilibrium - Wikipedia

    en.wikipedia.org/wiki/List_of_types_of_equilibrium

    Static equilibrium (economics), the intersection of supply and demand in any market Sunspot equilibrium , an economic equilibrium in which non-fundamental factors affect prices or quantities Underemployment equilibrium , a situation in Keynesian economics with a persistent shortfall relative to full employment and potential output

  9. Mechanical equilibrium - Wikipedia

    en.wikipedia.org/wiki/Mechanical_equilibrium

    A stationary object (or set of objects) is in "static equilibrium," which is a special case of mechanical equilibrium. A paperweight on a desk is an example of static equilibrium. Other examples include a rock balance sculpture, or a stack of blocks in the game of Jenga , so long as the sculpture or stack of blocks is not in the state of ...
