Technician A says axles with a numerically high gear ratio (such as 4.11)allow the engine to run slower at any given speed, resulting in better fuel conservation. Technician B says axles with a numerically low gear ratio (such as 2.83)allow for fast acceleration and good pulling power. Who is correct?
A)A only
B)B only
C)both A and B
D)neither A nor B

Question

Quizplus · Accepted Answer

Technician A is incorrect because axles with a numerically high gear ratio (such as 4.11) actually cause the engine to run faster at any given speed, which can decrease fuel efficiency but improve acceleration and pulling power. Technician B is incorrect because axles with a numerically low gear ratio (such as 2.83) result in slower acceleration but better fuel efficiency and higher top speed.
