Question

Solve the following automotive-services problems based on the examples shown previously. Choose the correct answer.

In first gear, or low gear, an automobile's engine runs about three times as fast as the drive shaft. In second gear, the engine does not have to run as fast; usually it runs about 1.6 times faster than the drive shaft. Finally, in third, or high gear, the engine runs at the same speed as the drive shaft.

Engine speed = 2,400 r.p.m.
Drive-shaft speed = 2,400 r.p.m.

Transmission in which gear ?

Answer 1

transmission must be in third gear as both are running at the same speed ! so third gear !!!

Answer 2

Transmission is in 3rd gear.

Explanation:

It's given in the question that in first gear, or low gear, an automobile's engine runs about 3 times as fast as the drive shaft.

In 2nd gear the engine runs about 1.6 times faster than the shaft drive.

But in third or higher gear the engine runs at the same speed as the drive shaft.

Engine speed = Drive shaft speed = 2400 r.p.m.

Therefore, transmission is in 3rd gear.
