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:
“Fear death?—to feel the fog in my throat,
The mist in my face,
When the snows begin, and the blasts denote
I am nearing the place,
The power of the night, the press of the storm,
The post of the foe;
Where he stands, the Arch Fear in a visible form,
Yet the strong man must go:”
—Robert Browning (1812–1889)
“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)
