Chapter 38, Problem 1RQ
What determines whether a conventional transmission or a transaxle is used?
Expert Solution & Answer
To determine
Whether a conventional transmission or transaxle is used in a vehicle.
Answer to Problem 1RQ
The type of drive system helps to determine either a transmission or transaxle is used.
Explanation of Solution
In a vehicle, the type of drive system helps in determining whether it is a conventional transmission or a transaxle. Both the transmission housing and transaxle uses a set of meshed gears of varying sizes to provide the engine various output torque and speed needed to drive the wheels. The vehicles that have rear wheel drive mainly use a conventional transmission and the vehicles with front-wheel drive use a transaxle.

The assembly shown consists of a weightless, rigid bar AC, pinned at B, that is attachedto the steel and aluminum rods. Initially, bar AC is in horizontal position; there is agap, Δ = 9 mm, between the lower end of the steel rod and its pin support at D.Neglecting the weight of the rods, compute their stresses when they are subjected to atemperature increase of 35°C and the lower end of the steel rod is attached to itssupport.
