The mechanic installs a new shock absorber on the car.

Definition

1. Noun:
   • A mechanical device designed to absorb and damp shock impulses: A "shock absorber" is a component, typically in a vehicle's suspension system, that converts the kinetic energy of a sudden jolt or bump into another form of energy (often heat), thereby smoothing out the ride and maintaining tire contact with the road.

Usage Examples

• Noun:
  • The mechanic recommended replacing the worn shock absorbers to improve the car's handling.
  • Modern mountain bikes are equipped with sophisticated shock absorbers to handle rough terrain.

Advanced Usage

• Technical Context: In engineering, "shock absorber" can refer to similar damping devices in non-automotive applications, such as in aircraft landing gear, industrial machinery, or even in the construction of buildings and bridges to mitigate seismic activity.
  • The building's design includes massive hydraulic shock absorbers to withstand earthquakes.

Variants and Related Words

• Shock (n, informal): A common shortened, informal term for a shock absorber, especially in automotive contexts.
  • My truck rides rough; I think I need new shocks.
• Damper (n): A more general term for any device that deadens, restrains, or depresses. A shock absorber is a specific type of damper.
• Strut (n): A structural component that often incorporates a shock absorber into a single assembly (e.g., a MacPherson strut).

Synonyms

• Damper: A device that reduces oscillation or shock.
• Cushion: Something that lessens the effect of an impact (though less technical).

Related Phrases

• To absorb shock: The verb phrase describing the primary function of the device.
  • The system's primary job is to absorb shock from the road.
