Hammer Throw
The hammer throw (HT for short) is one of the four throwing events in regular outdoor track-and-field competitions, along with the discus throw, shot put and Javelin throw, 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. These three components are each separate and can move independently. Both the size and weight of the ball vary between men's and women's events. The women's hammer weighs for college and professional meets while the men's hammer weighs . History Tradition traces it to the Tailteann Games (ancient), Tailteann Games in Hill of Tara, Tara, Ireland, around the year 1830 BC. Some time later the Celtic warrior Cú Chulainn, Culchulainn reputedly took a chariot axle with a wheel still attached, spun it around and hurled it a long way. The wheel was later replaced by a rock with a wooden handle attached. A sledgehammer began to be used for the sport in Scot ...

Centrifugal Force
Centrifugal force is a fictitious force in Newtonian mechanics (also called an "inertial" or "pseudo" force) that appears to act on all objects when viewed in a rotating frame of reference. It appears to be directed radially away from the axis of rotation of the frame. The magnitude of the centrifugal force ''F'' on an object of mass ''m'' at the perpendicular distance ''ρ'' from the axis of a rotating frame of reference with angular velocity is F = m\omega^2 \rho. This fictitious force is often applied to rotating devices, such as centrifuges, centrifugal pumps, centrifugal governors, and centrifugal clutches, and in centrifugal railways, planetary orbits and banked curves, when they are analyzed in a non–inertial reference frame such as a rotating coordinate system. The term has sometimes also been used for the '' reactive centrifugal force'', a real frame-independent Newtonian force that exists as a reaction to a centripetal force in some scenarios.

Latitude
In geography, latitude is a geographic coordinate system, geographic coordinate that specifies the north-south position of a point on the surface of the Earth or another celestial body. Latitude is given as an angle that ranges from −90° at the south pole to 90° at the north pole, with 0° at the Equator. Parallel (latitude), Lines of constant latitude, or ''parallels'', run east-west as circles parallel to the equator. Latitude and longitude are used together as a coordinate pair to specify a location on the surface of the Earth. On its own, the term "latitude" normally refers to the ''geodetic latitude'' as defined below. Briefly, the geodetic latitude of a point is the angle formed between the vector perpendicular (or ''Normal (geometry), normal'') to the ellipsoidal surface from the point, and the equatorial plane, plane of the equator. Background Two levels of abstraction are employed in the definitions of latitude and longitude. In the first step the physical surface i ...

Steroid
A steroid is an organic compound with four fused compound, fused rings (designated A, B, C, and D) arranged in a specific molecular configuration. Steroids have two principal biological functions: as important components of cell membranes that alter membrane fluidity; and as signal transduction, signaling molecules. Examples include the lipid cholesterol, sex hormones estradiol and testosterone, anabolic steroids, and the anti-inflammatory corticosteroid drug dexamethasone. Hundreds of steroids are found in Fungus, fungi, plants, and animals. All steroids are manufactured in cells from a sterols, sterol: Cholesterol, cholesterol (animals), lanosterol (opisthokonts), or cycloartenol (plants). All three of these molecules are produced via Cyclic compound, cyclization of the triterpene squalene. Structure The steroid nucleus (parent structure, core structure) is called gonane (cyclopentanoperhydrophenanthrene). It is typically composed of seventeen carbon atoms, bonded in fou ...

Grigory Rodchenkov
Grigory Mikhailovich Rodchenkov (; born 24 October 1958) is the former head of Russia's national anti-doping laboratory, the ''Anti-Doping Center''. Rodchenkov is known for his involvement in the state-run doping program in Russia. In November 2015, the Independent Commission of the World Anti-Doping Agency (WADA) determined that Rodchenkov was "at the heart of the positive drug test coverup", and that he had been directly involved with concealing positive tests and destroying 1,417 urine samples. Rodchenkov made headlines in 2016 after an interview to ''The New York Times'' exposing the doping program in Russia. Rodchenkov said he developed a three-drug cocktail of banned substances that he mixed with liquor and provided to dozens of athletes at the Sochi Olympics. Rodchenkov's allegations were confirmed by the independent McLaren Report, leading to Russia's partial bans from the 2016 Summer Olympics and 2018 Winter Olympics. Since the revelations became public, Rodchenkov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Circular Sector
A circular sector, also known as circle sector or disk sector or simply a sector (symbol: ⌔), is the portion of a disk (a closed region bounded by a circle) enclosed by two radii and an arc, with the smaller area being known as the ''minor sector'' and the larger being the ''major sector''. In the diagram, is the central angle, the radius of the circle, and is the arc length of the minor sector. The angle formed by connecting the endpoints of the arc to any point on the circumference that is not in the sector is equal to half the central angle. Types A sector with the central angle of 180° is called a '' half-disk'' and is bounded by a diameter and a semicircle. Sectors with other central angles are sometimes given special names, such as quadrants (90°), sextants (60°), and octants (45°), which come from the sector being one quarter, sixth or eighth part of a full circle, respectively. Area The total area of a circle is . The area of the sector can be obtai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
