Pronunciation: [swˈe͡ɪ bˈɑː] (IPA) 
The correct spelling of the term for a part of a car's suspension system is "sway bar". The word "sway" is pronounced /sweɪ/, with the "s" sound at the beginning followed by a "w" sound (/weɪ/). The word "bar" is pronounced /bɑː/, with a long "a" sound and the "r" sound at the end. Together, these two words form the term "sway bar", which refers to a metal bar used to reduce body roll during cornering.
A sway bar, also known as a stabilizer bar or anti-roll bar, is a crucial component of a vehicle's suspension system that helps to improve its stability and handling. It is typically a solid or tubular-shaped steel bar that is connected to the suspension components on both sides of the vehicle, usually near the front or rear axle.
The purpose of a sway bar is to reduce body roll or lateral sway during cornering or when the vehicle is maneuvering over uneven road surfaces. It accomplishes this by transferring the force between the left and right sides of the suspension, thus equalizing the weight distribution and minimizing the tilting or leaning of the vehicle.
When the vehicle experiences lateral forces, such as when turning a corner, the sway bar resists the body roll by twisting or flexing along its length. This torsional motion of the sway bar induces an opposite force on the suspension, which helps keep all four wheels planted firmly on the ground, increasing traction and stability.
A properly functioning sway bar enhances the vehicle's handling characteristics by reducing body roll, improving cornering grip, and minimizing the risk of oversteer or understeer. Moreover, it promotes uniform tire wear, as it ensures that the weight distribution remains balanced across all four wheels.
Sway bars come in varying thicknesses or diameters, depending on the vehicle's weight, suspension design, and desired handling characteristics. They can also be adjustable, allowing the driver to fine-tune the stiffness of the sway bar to suit their preferences or specific driving conditions.

The term "sway bar" is derived from the combination of two words: "sway" and "bar".
1. Sway: The word "sway" comes from the Old English word "swaeg", meaning "to move or swing gently from side to side". Over time, it evolved to refer to a rhythmic or oscillating motion.
2. Bar: In this context, the term "bar" refers to a solid, straight, and rigid component that is often made of metal. It is typically used to provide support, stability, or control within a mechanical system.
When combined, "sway bar" refers to a rigid bar that helps control or reduce the side-to-side movement (sway) of a vehicle's suspension. It is an essential component found in many automotive systems, designed to enhance stability and control during cornering or uneven road conditions.
