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:
“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)

Upon her to gaze:
But when he sawe how broade her beames did spredde
It did him amaze.”

“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.”
