Which of the following is a type of suspension system commonly found in vehicles?

Independent suspension is a commonly used type of suspension system in vehicles. This system allows each wheel to move up and down independently from the other wheels. The primary advantage of independent suspension is that it provides improved ride quality and handling, as it can adapt better to road conditions, which enhances the vehicle's stability and comfort during driving.

In independent suspension systems, components such as control arms, struts, and springs work in conjunction to enable this independent movement. This design reduces the impact of bumps and uneven surfaces on the vehicle, as the suspension of one wheel does not directly affect the others. This results in better traction, especially when turning, as weight distribution can be managed more effectively across the wheels.

Other types of suspension systems mentioned, such as air suspension, hybrid suspension, and hydraulic suspension, do exist but are not as universally applied as independent suspension. Air suspension uses air-filled bags instead of traditional springs, hydraulic suspension relies on fluid to adjust the vehicle's height and ride quality, and hybrid suspension typically combines different technologies. While they have their advantages and specific applications, independent suspension remains a foundational design in automotive engineering due to its effectiveness in enhancing vehicle dynamics and passenger comfort.
