Artist rendering of a NASCAR restrictor plate. A restrictor plate or air restrictor is a device installed at the intake of an engine to limit its power. This kind of system is occasionally used in road vehicles (e.g., motorcycles) for insurance purposes, but mainly in automobile racing, to limit top speed to provide equal level of competition, and to lower costs; insurance purposes have also ...
An ornate brass door hinge A barrel hinge. A hinge is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them. Two objects connected by an ideal hinge rotate relative to each other about a fixed axis of rotation, with all other translations or rotations prevented; thus a hinge has one degree of freedom.
The dihedral synchro-helix actuation door system is a type of door with a hinge mechanism which allows the doors to rotate 90° by sweeping outwards and upwards at the hinge. [1] It was designed and developed by Christian von Koenigsegg on behalf of high-performance sports cars manufacturer, Koenigsegg Automotive AB . [ 2 ]
By inserting a plastic hinge at a plastic limit load into a statically determinate beam, a kinematic mechanism permitting an unbounded displacement of the system can be formed. It is known as the collapse mechanism. For each degree of static indeterminacy of the beam, an additional plastic hinge must be added to form a collapse mechanism.
concrete hinge concrete hinge with front side notches. Concrete hinges are hinges produced out of concrete, with little or no steel in the hinge neck, which allows a rotation without a significant bending moment. [1] The high rotations [2] [3] result from controlled tensile cracks as well as creep.
With no moving parts, Tesla valves are much more resistant to wear and fatigue, especially in applications with frequent pressure reversal such as a pulsejet. [5]A micrograph of a Tesla valve in a fixed-valve micro-pump, with flow from right to left restricted [6]
The knee joints and ankle joints are less typical, as they allow a slight degree of rotation or side-to-side movement in certain positions of the limb. The knee is the largest hinge joint in the human body. Hinge and pivot joints are both types of synovial joint. A hinge joint can be considered a modified sellar/saddle joint, with reduced ...
Google Maps first started as a C++ program designed by two Danish brothers, Lars and Jens Eilstrup Rasmussen, and Noel Gordon and Stephen Ma, at the Sydney-based company Where 2 Technologies, which was founded in early 2003.
