The right front tire is worn on the outside and the vehicle pulls toward the right. technician a says that the camber on the right front may need to be adjusted. technician b says that caster on the right front may need to be adjusted. which technician is correct?

Technician A is correct

Explanation:

Front tires wear on outside edge because of wheel misalignment. Thus it is the Chamber that needs to be adjusted because Camber is the angle between the the tire's center line and actual vertical line(of road/car) viewed from the front of the vehicle.

Steering angle with respect to the wheel's center is called Caster.

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

i would think it's food chain
