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:
“Some are born great, some achieve greatness, and some have greatness thrust upon ‘em.”
—William Shakespeare (1564–1616)
“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)
“A man renowned for repartee
Will seldom scruple to make free
With friendship’s finest feeling,
Will thrust a dagger at your breast,
And say he wounded you in jest,
By way of balm for healing.”
—William Cowper (1731–1800)
