The Northrop Grumman E-2 Hawkeye is an American all-weather, carrier-capable tactical airborne early warning (AEW) aircraft. This twin-turboprop aircraft was designed and developed during the late 1950s and early 1960s by the Grumman Aircraft Company for the United States Navy as a replacement for the earlier, piston-engined E-1 Tracer, which was rapidly becoming obsolete.
The E2 class included several features found on other LB&SCR classes including an I2 class boiler to accommodate the Weir pump and hot water injector for use on high-pressure steam. [1] They had slotted frames, six small 4 ft 6 in (1.372 m) driving wheels, and a water tank capacity of 1,090 imp gal (5,000 L; 1,310 US gal).
Typically, it is written in the form x/y, where x is the percentage of weight in the front, and y is the percentage in the back. In a vehicle which relies on gravity in some way, weight distribution directly affects a variety of vehicle characteristics, including handling , acceleration , traction , and component life.
The EA/EB, E1, and E2 models were powered by twin 900 hp Winton 201A V-12 engines in each power unit. They were standardized mechanically and in overall design. Union Pacific's E2 cab unit was distinguished from the slant-nosed EA and E1 units by its bulbous nose, round porthole style windows, and stainless steel ornamentation on the pilot and ...

Lesser amount of unbalance correction weight in the final balancing process means lesser (concentrated) stress to the rotor assembly. Portable balancing machines are used to balance parts that cannot be taken apart and put on a balancing machine, usually parts that are currently in operation such as turbines, pumps, and motors. Portable ...
The EMD 645 is a family of two-stroke diesel engines that was designed and manufactured by the Electro-Motive Division of General Motors.While the 645 series was intended primarily for locomotive, marine and stationary engine use, one 16-cylinder version powered the 33-19 "Titan" prototype haul truck designed by GM's Terex division
BMX 3-Piece bottom brackets typically use a spindle either 19 mm or 19.05 mm (3/4″), 22 mm or 22.2 mm (7/8″), or 24 mm in diameter. The majority of newer or Asian parts are made to metric round numbers, and mixes of metric and non-metric (e.g. 19 mm and 19.05 mm) spindles and bearings may not be compatible, and can result in stuck parts.
