Thrust

Thrust is a reaction force described quantitatively by Newton's second and third laws. When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction on that system.

In mechanical engineering, force orthogonal to the main load (such as in parallel helical gears) is referred to as thrust.

Famous quotes containing the word thrust:

    An image of its state;
    The wings half spread for flight,
    The breast thrust out in pride
    Whether to play, or to ride
    Those winds that clamour of approaching night.
    William Butler Yeats (1865–1939)

    It was at a particular moment in the history of my own rages that I saw the Western world conditioned by the images of Marx, Darwin and Freud; and Marx, Darwin and Freud are the three most crashing bores of the Western world. The simplistic popularization of their ideas has thrust our world into a mental straitjacket from which we can only escape by the most anarchic violence.
    William Golding (b. 1911)

    I have always been, am, and propose to remain a mere scholar. All that I have ever proposed to myself is to say, this and this I have learned; thus and thus have I learned it; go thou and learn better; but do not thrust on my shoulders the responsibility for your own laziness if you elect to take, on my authority, conclusions the value of which you ought to have tested for yourself.
    Thomas Henry Huxley (1825–95)
