In thick metals, and when welding can be performed from both sides of the work piece, a double-V joint is used. When welding thicker metals, a double-V joint requires less filler material because there are two narrower V-joints compared to a wider single-V joint. Also the double-V joint helps compensate for warping forces.
A universal joint (also called a universal coupling or U-joint) is a joint or coupling connecting rigid shafts whose axes are inclined to each other. It is commonly used in shafts that transmit rotary motion. It consists of a pair of hinges located close together, oriented at 90° to each other, connected by a cross shaft.
The design is loosely based on the body shape of the Mosrite Mark 1 and its later iterations, though with a thinner and much lighter body. The top of the Hi-Flier headstock has two U-shaped cuts, echoing the three-notch "M" shape of the Mosrite. The pickguard shape and control layout also mimicked Mosrite.
A herringbone gear, a specific type of double helical gear, [1] is a side-to-side, rather than face-to-face, combination of two helical gears of opposite hands. [2] From the top, each helical groove of this gear looks like the letter V, and many together form a herringbone pattern (resembling the bones of a fish such as a herring ).
The twist-beam rear suspension (also torsion-beam axle, deformable torsion beam, or compound crank) is a type of automobile suspension based on a large H- or C-shaped member. The front of the H attaches to the body via rubber bushings , and the rear of the H carries each stub-axle assembly, on each side of the car.
Figure 2. Setup of the delayed-choice quantum-eraser experiment of Kim et al. Detector D 0 is movable. The experimental setup, described in detail in Kim et al., [1] is illustrated in Fig 2. An argon laser generates individual 351.1 nm photons that pass through a double-slit apparatus (vertical black line in the upper left corner of the diagram).
(Modern) electromagnetic seismograph: in 1855 Luigi Palmieri realizes a seismograph consisting of U-shaped tubes oriented on the different cardinal directions, filling them with mercury. When an earthquake shakes the ground, the motion of the mercury produces an electrical contact that stops a clock and at the same time starts a recording drum ...
The multiple-camera setup, multiple-camera mode of production, multi-camera or simply multicam is a method of filmmaking, television production and video production. Several cameras—either film or professional video cameras —are employed on the set and simultaneously record or broadcast a scene.
