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.
Suppose an engine is running 2,000 r.p.m. in second gear. How fast is the drive shaft running?
Drive shaft rotation = r.p.m.
i need the answer i don't wanna answer my own dang question
Solve the following automotive-services problem.
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 = 2,575 r.p.m.
Transmission in second gear
Drive-shaft speed (to nearest r.p.m.) = r.p.m.
To find the speed of the drive shaft when the engine is running at 2,000 r.p.m. in second gear, we can use the ratio between the engine speed and the drive shaft speed in second gear.
We are given that in second gear, the engine runs about 1.6 times faster than the drive shaft. So, if the engine is running at 2,000 r.p.m., we can calculate the drive shaft speed as follows:
Drive shaft rotation = Engine rotation / Ratio
Drive shaft rotation = 2,000 r.p.m. / 1.6
Drive shaft rotation = 1,250 r.p.m.
Therefore, the drive shaft is running at 1,250 r.p.m. when the engine is running at 2,000 r.p.m. in second gear.
