  2. Drawbar (machine tool) - Wikipedia

    en.wikipedia.org/wiki/Drawbar_(machine_tool)

    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.

  3. Lathe - Wikipedia

    en.wikipedia.org/wiki/Lathe

    Modern metal lathe A watchmaker using a lathe to prepare a component cut from copper for a watch. A lathe (/ l eɪ ð /) is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, threading and turning, with tools that are applied to the workpiece to create an object with symmetry about ...

  4. Powder-actuated tool - Wikipedia

    en.wikipedia.org/wiki/Powder-actuated_tool

    Ramset powder-actuated tool. A powder-actuated tool (PAT, often generically called a Hilti gun or a Ramset gun after their manufacturing companies) is a type of nail gun used in construction and manufacturing to join materials to hard substrates such as steel and concrete.

  5. Power (physics) - Wikipedia

    en.wikipedia.org/wiki/Power_(physics)

    Power in mechanical systems is the combination of forces and movement. In particular, power is the product of a force on an object and the object's velocity, or the product of a torque on a shaft and the shaft's angular velocity. Mechanical power is also described as the time derivative of work.

  6. T-carrier - Wikipedia

    en.wikipedia.org/wiki/T-carrier

    The T-carrier is a hardware specification for carrying multiple time-division multiplexed (TDM) telecommunications channels over a single four-wire transmission circuit. It was developed by AT&T at Bell Laboratories ca. 1957 and first employed by 1962 for long-haul pulse-code modulation (PCM) digital voice transmission with the D1 channel bank.

    The most common type of railway, where power is applied by driving some or all of the wheels of the locomotive. [4] Adhesive weight The weight on the driving wheels of a locomotive, which determines the frictional grip between wheels and rail, and hence the drawbar pull a locomotive can exert [5] Adjusting spring

  9. Attenuator (electronics) - Wikipedia

    en.wikipedia.org/wiki/Attenuator_(electronics)

    P in = V in I in = power entering the input port from the source. P out = V out I out = power absorbed by the load from the output port. P direct = the power that would be absorbed by the load if the load were connected directly to the source. L pad = 10 log 10 (P in / P out), always. Further, if Z s = Z Load, then L pad = 20 log 10 (V in / V ...
