Question

echnician a says that the torque available at the output shaft is greater in 2nd gear than when the transmission/transaxle is in 3rd gear at the same engine speed. technician b says that the output shaft is rotating faster when the transmission/transaxle is in 2nd gear compared to 3rd gear when the engine is at the same speed. which technician is correct?

Answer 1

Technician A is correct about the torque being greater in 2nd gear, while Technician B is incorrect as the output shaft speed is actually faster in 3rd gear versus 2nd gear, at the same engine speed.

Step-by-step explanation:

The question involves understanding the relationship between gear ratios and torque as well as output shaft speed in vehicles. Technician A is correct, as the torque available at the output shaft is indeed greater in 2nd gear than in 3rd gear at the same engine speed. This is because lower gears have a higher gear ratio, which increases torque but reduces the output shaft speed. Technician B, however, is incorrect. The output shaft rotates faster when the transmission/transaxle is in a higher gear, like 3rd gear, compared to a lower gear, like 2nd gear, assuming the engine speed is constant. This is because higher gears have a lower gear ratio, which decreases torque but increases speed.
