The Hyperlogos

In [automotive] terms, a Strut is a [shock absorber] (or [damper]) with a fixed mount at the non-shaft end rather than a [pivot]ing [link]. In all other ways, it is identical to an ordinary shock absorber.

Struts are most commonly associated with the [MacPherson strut suspension], a space, weight, and cost-saving suspension commonly found in the front of lightweight vehicles. It is typically used only for front suspension, but some cars have a MacPherson suspension, and thus struts, at all four corners.

Struts typically have two parts; The [body], which is simply a cylinder with the lower strut mount attached to it; and the [cartridge], a replaceable shock absorber. This minimizes the cost of replacement. Not all struts are designed in this fashion.
