The drawbar pull is an important component that allows the milling machine to keep the tool in place while it’s being used. The force from the drawbar pull supplied to the tool has to be just right because not enough force would cause the tool to wobble leading to inaccuracy, and too much force would apply excessive stress, leading to shorter tool life.
The E-100 series was a cost-reduced version of the A-100 introduced in 1965, with only one set of drawbars per manual, a reduced number of presets, and a slightly different tone generator. [62] This was followed by the H-100 series, with a redesigned tonewheel generator and various other additional features. [ 58 ]

Two methods of drawing smooth curves in manual drafting are the use of French curves and flat splines (flexible curves). A French curve is a drawing aid with many different smoothly-varying radiused curves on it; the manual drafter can fit the French curve to some known reference points and draw a smooth curved line between them.
A dog-trailer (also called a pup) is a short trailer with a permanent dolly, with a single A-frame drawbar that fits into the Ringfeder or pintle hook on the rear of the truck or trailer in front, giving the whole unit two or more articulation points and very little roll stiffness. These are commonly used in Australia, particularly for end ...

Thrust levers of an A320 set to the autothrust position during cruise flight. An autothrottle (automatic throttle; also known as autothrust, A/T, or A/THR) is a system that allows a pilot to control the power setting of an aircraft's engines by specifying a desired flight characteristic, rather than manually controlling the fuel flow.
