Question

Problem: The stick diagram of a RWD 5-speed MT is shown below. The final drive ratio is ia and the tire radius is R (ft.) a) Find the transmission ratios in forward and reverse gears in terms of the tooth numbers as labeled. b) What is the speed difference that needs to be synchronized in a 1-2 shift when the shift is made at a vehicle speed V (mph)? c) What is the speed difference that needs to be synchronized in a 5-4 shift when the shift is made at a vehicle speed (mph)? 5th-Rev.
