   After all, the purpose of the fifth wheel is to link the tractor and the trailer; indeed, trailers existed before Charles H. Martin introduced the Martin Rocking Fifth Wheel in 1915. At the time, the fifth wheel literally was a wheel that moved with the trailer—unlike today’s technology that secures a kingpin.

   In the 1930s, Walker invented a device which added a fifth wheel to cars to aid parallel parking. The extra wheel was mounted on the rear of the vehicle, at right angles to the rest of the wheels. When in use, the fifth wheel lifted the back of the car off its normal rear wheels, allowing the rear of the car to swing laterally. [2] [3]

7. Drawbar pull - Wikipedia

   en.wikipedia.org/wiki/Drawbar_pull

   In automotive engineering, drawbar pull is the amount of horizontal force available to a vehicle at the drawbar for accelerating or pulling a load.. Drawbar pull is a function of velocity, and in general decreases as the speed of the vehicle increases (due both to increasing resistance and decreasing transmission gear ratios).
