The 7 post shaker is a piece of test equipment used to perform technical analysis on racecars. A 7 post shaker can apply all vertical forces acting on the car on the racetrack, emulating some of the effects of driving. The shaker has many controls for the hydraulic system and sensors to measure forces and their effects on the car. The forces include banking loads, lateral load transfer, longitudinal weight transfer and ride height sensitive downforce.
Famous quotes containing the words post and/or shaker:
“My business is stanching blood and feeding fainting men; my post the open field between the bullet and the hospital. I sometimes discuss the application of a compress or a wisp of hay under a broken limb, but not the bearing and merits of a political movement. I make gruel—not speeches; I write letters home for wounded soldiers, not political addresses.”
—Clara Barton (1821–1912)
“Of the Shaker society, it was formerly a sort of proverb in the country, that they always sent the devil to market.”
—Ralph Waldo Emerson (1803–1882)
