How does a strut differ from a shock absorber?

A strut differs from a shock absorber primarily in its construction and function within the vehicle's suspension system. A strut is a structural component that not only serves the role of damping motion through a built-in shock absorber but also supports the weight of the vehicle. It often includes a coil spring, which helps absorb the impact from road irregularities and supports the vehicle's weight, thereby contributing to the overall structural integrity of the suspension system.

In contrast, a shock absorber, while it performs the vital function of damping the oscillations that occur due to road conditions, does not provide structural support. It works in conjunction with other components, such as springs, to manage the vehicle's ride quality and handling but lacks the integrated support that a strut offers. Understanding this distinction is crucial for anyone studying suspension systems, as it highlights the specific roles each component plays in vehicle dynamics.
