Which statement about the pitman arm is true?

The statement that the pitman arm is the strongest arm in the steering linkage system is accurate. The pitman arm is a critical component in the steering mechanism, connecting the steering gear to the center link of the steering system. Its primary function is to translate the rotational movement of the steering gear into the lateral motion needed to turn the wheels.

Given the significant forces acting on this part during steering operation, the pitman arm is designed to be robust and resilient, constructed typically from durable materials like steel. This design is essential to ensure that it can handle the dynamic loads experienced while maneuvering the vehicle, thus affirming its role as one of the strongest components in the steering linkage.

In this context, other options suggest inaccuracies; for instance, stating that the pitman arm is the weakest part of the steering system overlooks its structural design and purpose. Similarly, asserting that it is not connected to the steering gear is incorrect, as the pitman arm is directly attached to the gear, and claiming it is typically made of plastic belies the common use of metal for durability and strength in such critical applications.
