Final answer:
The toe-out-on-turns principle is controlled by angles manufactured into the steering arms, contributing to proper steering geometry and vehicle handling during turns.
Step-by-step explanation:
The correct answer is option a) Steering arms. The principle of toe-out-on-turns, which is essential for proper steering geometry and improved vehicle control during turns, is controlled by angles manufactured into the steering arms of a vehicle.
This concept, also closely associated with Ackerman steering geometry, ensures that during a turn, the inner wheel turns at a sharper angle than the outer wheel to accommodate the difference in turning radius. This reduces tire wear and improves the handling of the vehicle.
As the steering arms are directly connected to the wheels, they play a crucial role in achieving the correct angles required for this phenomenon.
In an automobile, the steering system is responsible for controlling the direction of the vehicle. The steering principle known as toe-out-on-turns refers to the angle at which the front wheels turn outwards during a turn.
This steering principle is controlled by angles manufactured into the Ackerman arms. The Ackerman arms are a part of the steering linkage system which connects the steering wheel to the front wheels.
The angle of the Ackerman arms ensures that the inside wheel of the vehicle follows a smaller turning radius compared to the outside wheel, resulting in better maneuverability and stability during turns.
