WebThat said, for any given point on a damping curve for a typical passenger car shock, you might see a c value of something like 1000-10000N/m/s. Super hard to say, really, since shocks are pretty non-linear, but as a not-very-helpful value it's about 0.5 to 0.8 depending on the application. Pneumatic and hydraulic shock absorbers are used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston (see below).
