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:
“I can forgive even that wrong of wrongs,
Those undreamt accidents that have made me
Seeing that Fame has perished this long while,
Being but a part of ancient ceremony
Notorious, till all my priceless things
Are but a post the passing dogs defile.”
—William Butler Yeats (1865–1939)
“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)
