Virtual Work

Virtual work arises in the application of the principle of least action to the study of forces and movement of a mechanical system. Historically, virtual work and the associated calculus of variations were formulated to analyze systems of rigid bodies, but they have also been developed for the study of the mechanics of deformable bodies.

Famous quotes containing the words virtual and/or work:

    Tragedy dramatizes human life as potentiality and fulfillment. Its virtual future, or Destiny, is therefore quite different from that created in comedy. Comic Destiny is Fortune—what the world will bring, and the man will take or miss, encounter or escape; tragic Destiny is what the man brings, and the world will demand of him. That is his Fate.
    Susanne K. Langer (1895–1985)

    They give us a pair of cloth shorts twice a year for all our clothing. When we work in the sugar mills and catch our finger in the millstone, they cut off our hand; when we try to run away, they cut off our leg: both things have happened to me. It is at this price that you eat sugar in Europe.
    Voltaire [François Marie Arouet] (1694–1778)
