steering ______ allows both wheels to move at slightly different angles when turning, avoiding any scrubbing.
caster.
ackermann.
axis inclination.
kingpin angle.
ok

Explanation:

The Ackermann steering geometry is designed so that during a turn, the inner and outer wheels turn at slightly different angles. This prevents tire scrubbing (unnecessary sliding of tires on the road surface) by ensuring each wheel follows its own circular path around the center of the turn. Caster is related to wheel alignment for stability, axis inclination (like camber) is about wheel tilt, and kingpin angle is about the steering axis tilt—these don't directly address the differential angle for turning to avoid scrubbing. So the correct answer is Ackermann.

Answer:

B. Ackermann (Note: Assuming the options are labeled, but in the given, the correct one is Ackermann. If the options were A: Caster, B: Ackermann, C: Axis inclination, D: Kingpin angle, then the answer is B. Ackermann)
