Question

Difficulty: EasySuspension Systems

When a vehicle makes a sharp turn, centrifugal force causes the chassis to lean toward the outside of the curve. Which suspension component is designed to reduce this body roll by transferring torsional resistance between the left and right wheels?

  1. A
    Shock absorber
  2. Stabilizer barAnswer
  3. C
    Differential assembly
  4. D
    Brake caliper

Answer

Stabilizer bar
The stabilizer bar (anti-roll bar or sway bar) is a transverse steel torsion rod linked to both sides of the suspension. When cornering causes one side of the vehicle to drop relative to the other, the bar twists and applies an equalizing force to reduce lateral body roll.

Step-by-Step Solution

1
Identify the primary suspension challenge presented in the scenario.
The vehicle experiences lateral weight transfer and body roll (lean) during a cornering maneuver.
Centrifugal forces compress the outside suspension while extending the inside suspension.
2
Evaluate the mechanical role of each listed automotive component.
A stabilizer bar (sway bar) connects both lower control arms across the chassis using a torsion spring rod that twists when one side compresses more than the other.
This torsional action resists chassis lean by pulling up on the outside control arm and pushing down on the inside control arm.
