2. Three-point hitch - Wikipedia

   en.wikipedia.org/wiki/Three-point_hitch

   The hydraulically operated and controlled three-point hitch used the draft of the mounted tool to moderate the depth of the tool and therefore the load on the tractor (automatic depth control or draft control). In addition, the three-point hitch would prevent the tractor from flipping backwards on the drive wheels if the implement being dragged ...

3. Tensionless hitch - Wikipedia

   en.wikipedia.org/wiki/Tensionless_hitch

   A Tensionless hitch is an anchor knot used for rappelling or rope rescue. Unlike most knots, the tensionless hitch retains a 100% efficiency rating, [ 3 ] meaning the strength of the knot is equal to the strength of the rope; it is not a significant stress riser .

4. Munter hitch - Wikipedia

   en.wikipedia.org/wiki/Munter_hitch

   The control rope (the rope not going to the load) is tied to the load rope with a mule knot (aka halter hitch) – not a noose (slipped overhand)! – and the bight (loop) that sticks out is tied in an overhand around the load rope. A carabiner is then sometimes clipped through the end of the bight and around the load rope.

5. Tow hitch - Wikipedia

   A tow hitch (or tow bar or trailer hitch in North America [1]) is a device attached to the chassis of a vehicle for towing, or a towbar to an aircraft nose gear. It can take the form of a tow ball to allow swiveling and articulation of a trailer , or a tow pin, or a tow hook with a trailer loop, often used for large or agricultural vehicles ...

6. Trucker's hitch - Wikipedia

   en.wikipedia.org/wiki/Trucker's_hitch

   Versions popular in East Asia use variations of sheep shank using either a simple half hitch [11] or a double turn self crossing half hitch [12] or a triple turn self crossing half hitch. [13] A sheep shank with two consecutive half hitches i.e. a clove hitch to secure the upper eye and to form the lower eye is more popular in the west.

7. Four-terminal sensing - Wikipedia

   en.wikipedia.org/wiki/Four-terminal_sensing

   Four-point measurement of resistance between voltage sense connections 2 and 3. Current is supplied via force connections 1 and 4. In electrical engineering, four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method is an electrical impedance measuring technique that uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurements ...
