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)
““To me it seems a shocking idea. I despise and loathe myself, and yet you thrust self at me from every corner of the church as though I loved and admired it. All religion does nothing but pursue me with self even into the next world.””
—Henry Brooks Adams (1838–1918)
“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)
