2. Bollard pull - Wikipedia

   en.wikipedia.org/wiki/Bollard_pull

   Bollard pull is a conventional measure of the pulling (or towing) power of a watercraft.It is defined as the force (usually in tonnes-force or kilonewtons (kN)) exerted by a vessel under full power, on a shore-mounted bollard through a tow-line, commonly measured in a practical test (but sometimes simulated) under test conditions that include calm water, no tide, level trim, and sufficient ...

   Congressman Hunter's office estimated it would cost US$33 million a year to ... (9.3 km/h; 5.8 mph) in 1-metre (3 ft 3 in) level ice, and a bollard pull of 200 ...

4. Force gauge - Wikipedia

   en.wikipedia.org/wiki/Force_gauge

   The same type of "weigh bar" can be used to measure horizontal loads and "drawbar pull" of wheeled/tracked or vehicles or "bollard pull" of boats or the "thrust" of jet engines when a proper "test rig" is designed and constructed to provide "frictionless" fore-aft movement of the load relative to the weigh bars.

5. Anchor handling tug supply vessel - Wikipedia

   en.wikipedia.org/wiki/Anchor_handling_tug_supply...

   The reference load used in the design and testing of the towing winch is twice the static bollard pull. Even if AHTS-vessels are customized for anchor-handling and towing, they can also undertake, for example, ROV ( remotely operated underwater vehicle ) services, safety/rescue services, and supply duties between mainland and offshore ...

7. Capstan equation - Wikipedia

   en.wikipedia.org/wiki/Capstan_equation

   The capstan equation [1] or belt friction equation, also known as Euler–Eytelwein formula [2] (after Leonhard Euler and Johann Albert Eytelwein), [3] relates the hold-force to the load-force if a flexible line is wound around a cylinder (a bollard, a winch or a capstan). [4] [1]

8. Tractive effort - Wikipedia

   en.wikipedia.org/wiki/Tractive_effort

   Tractive effort can be theoretically calculated from a locomotive's mechanical characteristics (e.g., steam pressure, weight, etc.), or by actual testing with strain sensors on the drawbar and a dynamometer car. Power at rail is a railway term for the available power for traction, that is, the power that is available to propel the train.

9. Voith Schneider Propeller - Wikipedia

   en.wikipedia.org/wiki/Voith_Schneider_Propeller

   The Voith Schneider propeller was originally a design for a hydro-electric turbine. [2] Its Austrian inventor, Ernst Schneider, had a chance meeting on a train with a manager at Voith's subsidiary St. Pölten works; this led to the turbine being investigated by Voith's engineers, who discovered that although it was no more efficient than other water turbines, Schneider's design worked well as ...
