Monday, September 6th, 2010
LaughtOutSoft asked:
A car auto cruises at 65mph. The effective radius of the road weheel and tire is 11.75 inches from the road surface to axle center. The transmission has a locking overdrive at a ratio of 1.06. The differential has a ratio of 3.71.
What’s the linear speed of in fpm of the road contact patch if the tires, the rotational speed of the road wheel in rpm, the rotational speed of the drive shaft in rpm and the rotational speed of the engine in rpm.

Please help.. I’ve been working on this assignment nonstop for 8 hours already and am exhausted, and I have no idea what all these words mean cos’ my crappy university’s professors don’t give a damn.
