Question

Which of the following eases the drive effort in steering the vehicle?

• A. Positive caster
• B. Positive camber
• C. Negative caster
• D. Toe-in

Hint:

Tip: Positive caster = stable but heavier steering; Negative caster = light steering but less stability!

Answer 1

The Correct Option is C

Caster is the angle formed by the steering axis when viewed from the side of the vehicle.
A positive caster provides better straight-line stability but increases steering effort.
On the other hand, a negative caster reduces the effort required to steer the wheels.
This is why vehicles designed for easy maneuvering at low speeds, such as older cars or lightweight vehicles, often have a slight negative caster.
However, excessive negative caster can reduce directional stability at higher speeds.
Options like toe-in or positive camber primarily affect tyre wear and vehicle handling but not directly the steering effort.
Therefore, the correct answer is Negative caster.
