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)
“There are few things more difficult than to appraise the work of a man suddenly dead in his youth; to disentangle “promise” from achievement; to save him from that sentimentalizing which confuses the tragedy of the interruption with the merit of the work actually performed.”
—Ezra Pound (1885–1972)
