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:
“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)
“Freedom of choice for women, at the expense of the caring, warmth, and sensitivity to others so often associated with them, may be empty. In the thrust to redefine male and female roles, women must not become men; nor can men be permitted the continual dehumanization of their roles.”
—Kathleen Weibel (b. 1945)
““I sawe Phoebus thrust out his golden hedde,
Upon her to gaze:
But when he sawe how broade her beames did spredde
It did him amaze.”
—Edmund Spenser (1552?–1599)
