  2. Mounting block - Wikipedia

    en.wikipedia.org/wiki/Mounting_block

    A horse is best mounted using a mounting block because it is easier for the rider to mount the horse, it puts less strain on the stirrup leathers when mounting and it decreases the chances of the saddle slipping to one side when mounting, thereby reducing the chances of a fall and possible injury to the rider. A horse or pony is mounted from ...

  3. Organic radical battery - Wikipedia

    en.wikipedia.org/wiki/Organic_radical_battery

    Since this half-reaction is not readily reversible as the half-reaction at the positive electrode, several research groups have steered away from using pure organic radical batteries and instead use metal/ORB hybrid batteries usually consist of a radical polymer cathode and the same anode found in rechargeable Li-ion batteries.

    Orbital-2, [4] [5] also known as Orb-2, was the third flight of the Orbital Sciences' uncrewed resupply spacecraft Cygnus, its third flight to the International Space Station, and the fourth launch of the company's Antares launch vehicle. The mission launched from the Mid-Atlantic Regional Spaceport (MARS) on 13 July 2014 at 16:52:14 UTC.

  5. O.R.B: Off-World Resource Base - Wikipedia

    en.wikipedia.org/wiki/O.R.B:_Off-World_Resource_Base

    As with most strategy games, the object of O·R·B is to defeat the enemy forces by gathering resources to build an attack fleet. As the name of the game implies, this is done by locating resource-bearing asteroids which must be mined to finance construction of new units.

    Cygnus Orb-3 spacecraft integrated with Antares rocket. This would have been the third of eight flights by Orbital Sciences under the Commercial Resupply Services (CRS-1) contract with NASA . This was the first attempted flight of the Antares 130 , which uses a more powerful Castor 30XL second stage, and the last flight of the standard-sized ...

  8. Railgun - Wikipedia

    en.wikipedia.org/wiki/Railgun

    In 2010, the United States Navy tested a BAE Systems-designed compact-sized railgun for ship emplacement that accelerated a 3.2 kg (7 pound) projectile to hypersonic velocities of approximately 3,390 m/s (7,600 mph; 12,200 km/h; 11,100 ft/s), or about Mach 10, with 18.4 MJ of kinetic energy. It was the first time in history that such levels of ...

  9. Spot welding - Wikipedia

    en.wikipedia.org/wiki/Spot_welding

    Typically the sheets are in the 0.5 to 3 mm (0.020 to 0.118 in) thickness range. Forcing a large current through the spot will melt the metal and form the weld. The attractive feature of spot welding is that a large amount of energy can be delivered to the spot in a very short time (approximately 10–100 milliseconds). [ 2 ]
