Nfirst 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 = 1,850 r. p.m. transmission in second gear drive-shaft speed =

Consider the following cases

Case 1: In n first gear,  an automobile's engine runs about three times as fast as the drive shaft.

So, if Speed of Engine = 1,850 r.p.m

Then Speed of Drive Shaft   r.p.m

Case 2 : In second gear, the engine does not have to run as fast; usually it runs about 1.6 times faster than the drive shaft.

 So, if Speed of Engine = 1,850 r.p.m

Then Speed of Drive Shaft   r.p.m

Case 3:  Finally, in third, or high gear, the engine runs at the same speed as the drive shaft.

So, if Speed of Engine = 1,850 r.p.m

Then Speed of Drive Shaft is also equal to 1,850 r.p.m
