In suspension testing, that helps isolate how stiffness and damping (the “k and c stuff”) respond without the complications of high-frequency motion.","simplifiedExplanation":"Quasi static means the test is done slowly enough that you’re mostly measuring basic stiffness and damping, not fast bouncing or vibration."}},{"startTime":1918.0,"endTime":1935.7,"type":"concept","title":"four poster","url":"/glossary/four-poster","quote":"...so that would be different right so that would be like on a like on a four poster where it's more dynamic okay okay yeah so this this yeah this rig is measuring all that stuff...","canonicalId":"concept:four-poster","priority":0.85,"confidence":0.9,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"A four-poster rig supports the car at multiple points (typically the wheels) and can apply controlled motion to study suspension compliance and body movement.

It’s a key behavior engineers watch for because it can reduce effective grip and make the ride feel unstable.","simplifiedExplanation":"Wheel hop is when a wheel starts to bounce or chatter quickly instead of staying planted.

Softer settings let the suspension move more, while firmer settings reduce bounce and wheel shake. Adjusting them can noticeably change ride quality and stability.","simplifiedExplanation":"Shocks control how the car moves after hitting bumps. If they’re set too soft, the car can bounce and feel shaky; if they’re set firmer, it settles down faster.
