A winch is a mechanical device that is used to pull in or let out or otherwise adjust the tension of a rope or wire rope.
Grind is the cross-sectional shape of a blade.
An automatic transmission is a multi-speed transmission used in motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. Vehicles with internal combustion engines, unlike electric vehicles, require the engine to operate in a narrow range of rates of rotation, requiring a gearbox, operated manually or automatically, to drive the wheels over a wide range of speeds.
A manual transmission (MT), also known as manual gearbox, standard transmission, or stick shift, is a multi-speed motor vehicle transmission system, where gear changes require the driver to manually select the gears by operating a gear stick and clutch.
A conventional fixed-wing aircraft flight control system (AFCS) consists of flight control surfaces, the respective cockpit controls, connecting linkages, and the necessary operating mechanisms to control an aircraft's direction in flight. Aircraft engine controls are also considered flight controls as they change speed.
A semi-automatic transmission is a multiple-speed transmission where part of its operation is automated, but the driver's input is still required to launch the vehicle from a standstill and to manually change gears. Semi-automatic transmissions were almost exclusively used in motorcycles and are based on conventional manual transmissions or sequential manual transmissions, but use an automatic clutch system. But some semi-automatic transmissions have also been based on standard hydraulic automatic transmissions with torque converters and planetary gearsets.
A burr mill, or burr grinder, is a mill used to grind hard, small food products between two revolving abrasive surfaces separated by a distance usually set by the user. When the two surfaces are set far apart, the resulting ground material is coarser, and when the two surfaces are set closer together, the resulting ground material is finer and smaller. Often, the device includes a revolving screw that pushes the food through. It may be powered electrically or manually.
SRAM LLC is a privately owned bicycle component manufacturer based in Chicago, Illinois, United States, founded in 1987. SRAM is an acronym comprising the names of its founders. The company produces a range of cycling components, including Grip Shift, and separate gravel, road, and mountain drivetrains from 7 to 12 speed. SRAM developed the Eagle line of mountain bike specific drivetrain components intended to improve shifting performance. SRAM was also the first to release a dedicated "one by" drivetrain with a single front chainring for road bikes.
A hydraulic brake is an arrangement of braking mechanism which uses brake fluid, typically containing glycol ethers or diethylene glycol, to transfer pressure from the controlling mechanism to the braking mechanism.
A jig grinder is a machine tool used for grinding complex shapes and holes where the highest degrees of accuracy and finish are required.
Vertical roller mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dressing processes, paints, pyrotechnics, cements and ceramics. It is an energy efficient alternative for a ball mill.
Active heave compensation (AHC) is a technique used on lifting equipment to reduce the influence of waves upon offshore operations. AHC differs from Passive Heave Compensation by having a control system that actively tries to compensate for any movement at a specific point, using power to gain accuracy.
The 1977 Herbert Pell Cup was held in Newport, Rhode Island, United States in 1977. The winner, Australia, was awarded the Herbert Pell Cup and went on to challenge for the 1977 America's Cup.
The 2017 America's Cup was the 35th staging of the America's Cup yacht race. The challenger, Emirates Team New Zealand, won by a score of 7 to 1 over the defender, Oracle Team USA. It was held on the Great Sound in Bermuda from June 17 to June 26. The races were conducted using hydrofoiling AC50 America's Cup Class yachts, which are slightly larger than the AC45F yachts used in the 2015–16 America's Cup World Series.
The AC50 was a wingsail catamaran development rule that governed the construction of the yachts used in the 2017 Louis Vuitton Cup and the 2017 America's Cup. Like the larger AC72s used in the 2013 America's Cup, AC50s used L-shaped daggerboard stabilizers as well as T-shaped rudder elevators that were able to generate enough lift to allow the boats to exit displacement mode in winds in excess of 7kt. Prototype versions of crossbeams, wingsails, appendages, as well as steering and trimming systems had been tested by all syndicates on AC45 platforms as surrogate yachts before building their AC50. The class allowed hydraulic control of the wingsails and appendages. Motors and computer automation was banned in the class. Each challenger team was only allowed to build one AC50 for competition and only six boats were built. The class was replaced with the monohull AC75 after the 2017 America's Cup.
Andrew Maloney is a New Zealand professional sailor born on 2 June 1990.
Sean Clarkson is a New Zealand sailor who has sailed at the Summer Olympics and in multiple Whitbread Round the World Races and America's Cups.
The C&C 37/40 is a Canadian 12.05 metres (39.5 ft) LOA fibreglass monohull sailing yacht, designed in 1988 by Robert W. Ball of Cuthbertson & Cassian as a replacement for the earlier C&C 37 dating from 1981. The C&C 37/40 is a recreational keelboat of moderate displacement, intended as a cruiser/racer or oceangoing racer. The yachts have a masthead sloop rig, with a fin keel and an internally-mounted spade-type rudder. Over 110 of the 37/40 type were built before the Canadian plant closed in 1994. The design is no longer produced.
Carl (Tiny) Whiting, born 1981 in Auckland, is a New Zealand sailor who has competed at the Summer Olympics and in multiple America's Cups.
The F50 is a one-design foiling catamaran used in the SailGP race series. The name is an abbreviation of "Foiling" and "a hull length of 50 feet". The F50s are adapted from the AC50s used in the America's Cup, with modifications including new control systems and modular wingsails. The F50s are one of the fastest racing classes in history, with a predicted top speed of 52.2 knots ; the current F50 speed record, achieved by the France SailGP Team at the Range Rover France Sail Grand Prix in 2022, stands at 53.96 knots. On July 18 2024 Canada SailGP Team achieved a top speed of 55.06 knots whilst testing new T-shaped foils, to replace L-shaped foils, in San Francisco.
