A power rack (also known as a power cage, squat cage or squat rack) is a piece of weight training equipment that functions as a mechanical spotter for free weight barbell exercises without the movement restrictions imposed by equipment such as the Smith machine. Its general design is four upright posts with two adjustable horizontal bar catches ...

The ETSI rack is defined by the European Telecommunications Standards Institute (ETS 300 119). The distance of the right edge of the right mounting rail to the left edge of the left mounting rail is 535 millimetres (21.1 in). As 535 mm is very close to 21 inches, these racks are sometimes called 21-inch racks. The gap between the posts is 500 ...
Open Rack is an Open Compute Project standard [1] for a new rack and power delivery architecture and an efficient, scalable alternative to the EIA-310 19-inch rack. It differs from the traditional EIA-310 rack in that it was designed specifically for large-scale cloud deployments. There are four key features that make this rack design more ...
A rack and pinion has roughly the same purpose as a worm gear with a rack replacing the gear, in that both convert torque to linear force. However the rack and pinion generally provides higher linear speed — since a full turn of the pinion displaces the rack by an amount equal to the pinion's pitch circle whereas a full rotation of the worm screw only displaces the rack by one tooth width.

For Lotus's use, the Renault engine was given a number of key improvements, including a higher compression ratio (10.25 instead of 8.6), larger inlet valves, revised valve timings, dual valve springs and a twin-barrel carburettor. These changes lifted the engine's power by 23% from 63 hp (47 kW) at 5,000 rpm to 82 hp (61 kW) at 6,000 rpm.
This is not true globally, as for example in Togo, metal racks still cost less per installed unit power even with a lower tilt angle allowing for smaller wood beams. [4] The relative price of wood to metal radically shifts the optimal PV racking material throughout the world. [16] This can change as wood prices have been very volatile. [17]
