The Ackermann principle angles the steering __ toward the center of the rear of the vehicle.such that imaginary lines drawn from the center of the steering knuckle pivot points through the center of the outer tie-rod ends intersect at the center of the rear axle. a. Knuckles b. Hands c. Arms d. Linkage

## Step 1<br />The problem is about the Ackermann principle, which is a concept in automotive engineering. The principle involves the steering of a vehicle, where imaginary lines drawn from the center of the steering knuckle pivot points through the center of the outer tie-rod ends intersect at the center of the rear axle.<br />## Step 2<br />The question asks us to identify the correct term that fits the description given in the problem. The options are: a. Knuckles, b. Hands, c. Arms, d. Linkage.<br />## Step 3<br />The term that fits the description given in the problem is 'Linkage'. The Ackermann principle involves the linkage of the steering system, which is the connection between the steering knuckle pivot points and the outer tie-rod ends.
