What component allows a semi-independent suspension to have a certain degree of twist? A) Cross member B) Spring C) Wheel hub D) Wheel

The correct answer is B) Spring. Springs in a semi-independent suspension system provide the necessary flexibility and elasticity, allowing each wheel to move independently while maintaining a connection with the vehicle's chassis. This design enables wheels to twist or travel vertically over uneven terrain, thus enhancing ride comfort and vehicle stability. In real-world scenarios, semi-independent suspensions are often utilized in smaller cars and some SUVs to strike a balance between ride quality and handling performance. This configuration allows for a smoother ride while still retaining a level of handling precision, making it a popular choice among manufacturers looking to optimize design for varied driving conditions.
