torsion-bar

A mechanic installs a torsion-bar suspension on a truck.

Definition

1. Noun:
   • A mechanical spring: A "torsion-bar" is a long, straight metal bar that acts as a spring by twisting along its length. It is designed to resist torsional (twisting) forces and store mechanical energy.

Usage Examples

• Noun:
  • The car's suspension system uses a torsion-bar to absorb shocks from the road. (The metal bar twists to cushion the vehicle.)
  • Engineers replaced the broken torsion-bar in the heavy machinery. (They installed a new twisting spring component.)

Advanced Usage

• "torsion-bar suspension": a type of vehicle suspension that relies on a torsion-bar to support the chassis.

  • Many military vehicles use torsion-bar suspension for its durability and simplicity. (The system uses twisting bars instead of coil springs.)

• "torsion-bar spring rate": the measurement of how much resistance the bar provides per degree of twist.

  • Adjusting the torsion-bar spring rate can change the ride height of the truck. (Changing the twist resistance alters the vehicle's clearance.)

Variants and Related Words

• Torsion (n): the act of twisting or the state of being twisted.

  • The metal rod failed due to excessive torsion. (Too much twisting caused the rod to break.)

• Torsional (adj): relating to or involving torsion.

  • The torsional strength of the bar is critical for safety. (The bar's ability to resist twisting is important.)

Synonyms

• Twist bar: a less common term for a torsion-bar, emphasizing its twisting action.
• Anti-roll bar: a related component in vehicles that reduces body roll, though it works differently.
