hammer throw
Hammer throw
The hammer throw is one of the four throwing events in regular track and field competitions, along with the discus throw, shot put and javelin.
 The "hammer" used in this sport is not like any of the tools also called by that name.
 It consists of a metal ball attached by a steel wire to a grip.
 The size of the ball varies between men's and women's competitions (see Competition section below for details).
Rakesh Kumar Yadav
Rakesh Kr Yadav (born 2 October 1977) is an Indian track and field athlete from Uttar Pradesh who specializes in Hammer throw.
 Kumar set the Indian National record of 70.16m in the discipline on 17 July 2003 during the Second National Athletic Circuit Meet in Bangalore.
 He erased the 70.13 metre mark of Ishtiaq Ahamed set there in the year 2000.
Paper clip
A paper clip (or sometimes paperclip) is an instrument used to hold sheets of paper together, usually made of steel wire bent to a looped shape.
 Most paper clips are variations of the "Gem" type introduced in the 1890s or earlier, characterized by the almost two full loops made by the wire.
 Common to paper clips proper is their utilization of torsion and elasticity in the wire, and friction between wire and paper.
 When a moderate number of sheets are inserted between the two "tongues" of the clip, the tongues will be forced apart and cause torsion in the bend of the wire to grip the sheets together. Arresting gear
An Arresting gear, or arrestor gear, is a mechanical system used to rapidly decelerate an aircraft as it lands.
 Arresting gear on aircraft carriers is an essential component of naval aviation, and it is most commonly used on CATOBAR and STOBAR aircraft carriers.
 Similar systems are also found at land-based airfields for expeditionary or emergency use.
 Typical systems consist of several steel wire ropes laid across the aircraft landing area, designed to be caught by an aircraft's tailhook.
 During a normal arrestment, the tailhook engages the wire and the aircraft's kinetic energy is transferred to hydraulic damping systems attached below the carrier deck.
 There are other related systems which use nets to catch aircraft wings or landing gear.
 These "barricade" and "barrier" systems are only used for emergency arrestments for aircraft without operable tailhooks. Stubs Iron Wire Gauge
The Stubs Iron Wire Gauge system (also known as the Birmingham Wire Gauge and not the same as, though similar to, the Stubs Steel Wire Gauge) is used to specify thickness or diameter of metal wire, strip, and tube products.
 The Stubs system was the first wire gauge recognized as a standard by any country when Great Britain adopted it in 1884; though nearly obsolete, it is the only wire gauge recognized in the United States through an Act of Congress. Wire brush
A wire brush is a tool consisting of a brush whose bristles are made of wire, most often steel wire.
 The steel used is generally a medium- to high-carbon variety and very hard and springy.
 Other wire brushes feature bristles made from brass or stainless steel, depending on application.
 Wires in a wire brush can be held together by epoxy, staples, or other binding.
 Wire brushes usually either have a handle of wood or plastic (for handheld use) or are formed into a wheel for use on angle grinders, bench grinders, pistol-grip drill motors, or other power tools. Valmara 59
The Valmara 59 is a large cylindrical Italian bounding anti-personnel mine.
 It is the first in the "Valmara" family of mines produced by Valsella Meccanotecnica, and was followed by the Valmara 69 and VS-JAP.
 The mine's body is metal with a distinctive five-pronged head.
 The central prong has a hole, to allow the threading a trip wire.
 The inner body of the mine has a main charge surrounded with approximately 1,000 steel cubes, below which is a steel wire connecting it to the base of the mine.
 When the mine is triggered a small charge launches the mine into the air approximately 45 cm before the steel wire is pulled taut, the jolt of which pulls a striker into the detonator.
 A secondary time fuse triggers the mine after three seconds if it has not detonated after being triggered. Chicken wire
Chicken wire, or poultry netting, is a mesh of wire commonly used to fence poultry livestock, such as chickens, in a run or coop.
 It is made of thin, flexible galvanized steel wire, with hexagonal gaps.
 Available in 1 inch (about 2.5 cm) diameter, 2 inch (about 5 cm) and 1/2 inch (about 1.3 cm), chicken wire is available in various wire gauges usually 19 gauge (about 1 mm wire) to 22 gauge (about 0.7 mm wire).
 Chicken wire is occasionally used to build inexpensive cages for small animals (or to protect plants and property "from" animals) though the thinness and zinc content of galvanized wire may be inappropriate for animals prone to gnawing and will not keep out predators. Pedro's Cup
The Pedro's Cup is a biannual athletics event of two legs, which features an indoor track and field competition in January or February and an outdoor competition during the European summer period.
 The first competition of each year since 2005 has taken place in Bydgoszcz, Poland.
 The second competition of each year has taken place in another city, currently Poznan, Warsaw and Szczecin have hosted the summer/autumn Pedro's cup competition.
 The event typically draws top level competition, including at least fifteen Olympic medalists in 2008 and more in 2009.
 The meet is unique because it draws best athletes of the world to compete in a rather cold climate. Wire gauze
A Wire gauze is a sheet of thin metal that has net-like crosses or a wire mesh.
 Wire gauze is placed on the support ring that is attached to the retort stand between the Bunsen burner and the beakers in order to support the beakers or other glassware or flasks during heating.
 Moreover, the glassware has to be flat-bottomed to stay on the wire gauze.
 The wire gauze is made of a .
 This type of material provides long life expectancy and can be used over and over again without a risk of it being torn.
 The sides/corners of the wire gauze are turned inward to help prevent fraying, improve handling and reduce safety risk from protruding ends of wire.
 The wire gauze is an important piece of supporting equipment in a laboratory because beakers or any type of glassware cannot be heated directly with a flame from the Bunsen burner, and the wire gauze will help protect the glassware.
 There are two types of wire gauze: woven wire gauze and a wire gauze with a ceramic center.
 These two types of wire gauze that are made of metal have the same ability to transmit the heat efficiently, but the gauze with a ceramic center will allow the heat to be dispersed more evenly.
 The ceramic at the center of the wire gauze is enmeshed at high pressure to prevent it from peeling.
 There are three sizes of wire gauze with ceramic center: 4 inches, 5 inches, and 6 inches, so that different sizes of glassware can be accommodated.
