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:

    Neither dead nor alive, the hostage is suspended by an incalculable outcome. It is not his destiny that awaits for him, nor his own death, but anonymous chance, which can only seem to him something absolutely arbitrary.... He is in a state of radical emergency, of virtual extermination.
    Jean Baudrillard (b. 1929)

    You live on hopes, I guess. You always dream that someday you might have a lot of money, your ship might come in. But if the ship doesn’t come in, I’m going to work as long as I can.
    Marion Gray (b. c. 1914)
