Which statement about a solid-axle, or non-independent, suspension is true?

A solid-axle or non-independent suspension consists of a rigid axle that connects two wheels on the same axle, meaning that both wheels move together as a single unit. When one wheel encounters a bump, it causes the other wheel to be affected as well due to the rigid connection. This is why the statement about the impact on the opposite wheel is accurate. The design leads to a situation where the suspension system operates as a whole, resulting in synchronized movement of both wheels.

In contrast, independent suspension allows each wheel to move independently, which can lead to better handling and ride quality, especially on uneven surfaces. However, solid axles are often favored in specific applications like heavy-duty trucks or off-road vehicles because of their durability and load-carrying capacity. The impact on both wheels when one is displaced is a defining characteristic of solid-axle systems and highlights important considerations in suspension design concerning vehicle dynamics and ride performance.
