Crossbow (PSF)
A crossbow is a ranged weapon using an Elasticity (physics), elastic launching device consisting of a Bow and arrow, bow-like assembly called a ''prod'', mounted horizontally on a main frame called a ''tiller'', which is hand-held in a similar fashion to the stock (firearms), stock of a long gun. Crossbows shoot arrow-like projectiles called ''crossbow bolt, bolts'' or ''quarrels''. A person who shoots crossbow is called a ''crossbowman'' or an ''arbalist (crossbowman), arbalist'' (after the arbalest, a European crossbow variant used during the 12th century). Crossbows and bows use the same launch principle, but an archer using a longbow must maintain its bow draw, draw by pitching the bowstring with fingers, pulling it back with arm and back muscles, and then holding that form (exercise), form while aiming, which demands significant physical strength. A crossbow has a locking mechanism to maintain the draw, limiting the shooter's exertion to pulling the string into the lock and ...

Trigger (firearms)
A trigger is a mechanism that actuates the function of a ranged weapon such as a firearm, airgun, crossbow, or speargun. The word may also be used to describe a switch that initiates the operation of other non-shooting devices such as a trap, a power tool or a quick release. A small amount of energy applied to the trigger leads to the release of much more energy. Most triggers use a small flattened lever (called the ''trigger blade'') depressed by the index finger, but some weapons such as the M2 Browning machine gun or the Iron Horse TOR ("thumb-operated receiver") use a push-button-like thumb-actuated trigger design, and others like the Springfield Armory M6 Scout use a squeeze-bar trigger similar to the "ticklers" on medieval European crossbows. Although the word "trigger" technically implies the entire mechanism (known as the ''trigger group''), colloquially it is usually used to refer specifically to the trigger blade. Most firearm triggers are "single-action", meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noix Corde Carreau Arbalette
A walnut is the edible seed of a drupe of any tree of the genus ''Juglans'' (family Juglandaceae), particularly the Persian or English walnut, ''Juglans regia''. Although culinarily considered a "nut" and used as such, it is not a true botanical nut. After full ripening, the shell is discarded and the kernel is eaten. Nuts of the eastern black walnut (''Juglans nigra'') and butternuts (''Juglans cinerea'') are less commonly consumed. Characteristics Walnuts are rounded, single-seeded stone fruits of the walnut tree commonly used for food after fully ripening between September and November, in which the removal of the husk at this stage reveals a browning wrinkly walnut shell, which is usually commercially found in two segments (three or four-segment shells can also form). During the ripening process, the husk will become brittle and the shell hard. The shell encloses the kernel or meat, which is usually made up of two halves separated by a membranous partition. The seed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shooting Sport
Shooting sports is a group of competitive and recreational sporting activities involving proficiency tests of accuracy, precision and speed in shooting — the art of using ranged weapons, mainly small arms (firearms and airguns, in forms such as handguns, rifles and shotguns) and bows/crossbows. Shooting sports can be categorized by equipment, shooting distances, targets, time limits and degrees of athleticism involved. Shooting sports may involve both team and individual competition, and team performance is usually assessed by summing the scores of the individual team members. Due to the noise of shooting and the high (and often lethal) impact energy of the projectiles, shooting sports are typically conducted at either designated permanent shooting ranges or temporary shooting fields in the area away from settlements. History Great Britain Historically, shooting game and target shooting has been limited to the upper-class and the gentry, with severe penalties for poach ...

Firearm
A firearm is any type of gun designed to be readily carried and used by an individual. The term is legally defined further in different countries (see Legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the Siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stability. Modern firearms can be described by their caliber ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siege Engine
A siege engine is a device that is designed to break or circumvent heavy castle doors, thick city walls and other fortifications in siege warfare. Some are immobile, constructed in place to attack enemy fortifications from a distance, while others have wheels to enable advancing up to the enemy fortification. There are many distinct types, such as siege towers that allow foot soldiers to scale walls and attack the defenders, battering rams that damage walls or gates, and large ranged weapons (such as ballistae, catapults/trebuchets and other similar constructions) that attack from a distance by launching projectiles. Some complex siege engines were combinations of these types. Siege engines are fairly large constructions – from the size of a small house to a large building. From antiquity up to the development of gunpowder, they were made largely of wood, using rope or leather to help bind them, possibly with a few pieces of metal at key stress points. They could launch simple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ballista
The ballista (Latin, from Greek βαλλίστρα ''ballistra'' and that from βάλλω ''ballō'', "throw"), plural ballistae, sometimes called bolt thrower, was an ancient missile weapon that launched either bolts or stones at a distant target. Developed from earlier Greek weapons, it relied upon different mechanics, using two levers with torsion springs instead of a tension prod (the bow part of a modern crossbow). The springs consisted of several loops of twisted skeins. Early versions projected heavy darts or spherical stone projectiles of various sizes for siege warfare. It developed into a smaller precision weapon, the '' scorpio'', and possibly the ''polybolos''. Greek weapon The early ballistae in Ancient Greece were developed from two weapons called oxybeles and gastraphetes. The gastraphetes ('belly-bow') was a handheld crossbow. It had a composite prod and was spanned by bracing the front end of the weapon against the ground while placing the end of a slider ...

War Of The Heavenly Horses
The War of the Heavenly Horses () or the Han–Dayuan War () was a military conflict fought in 104 BC and 102 BC between the Chinese Han dynasty and the Saka-ruled (Scythian) Greco-Bactrian kingdom known to the Chinese as Dayuan, in the Ferghana Valley at the easternmost end of the former Persian Empire (between modern-day Uzbekistan, Kyrgyzstan and Tajikistan). The war was allegedly instigated by trade disputes compounded by the extended geopolitics surrounding the Han-Xiongnu War, resulting in two Han expeditions that eventuated in a decisive Han victory, allowing Han China to expand its hegemony deep into Central Asia (then known to the Chinese as the Western Regions). Reprinted as an advertisement feature: Emperor Wu of Han had received reports from diplomat Zhang Qian that Dayuan owned fast and powerful Ferghana horses known as the "heavenly horses", which would help greatly with improving the quality of their cavalry mounts when fighting the Xiongnu horse nomads, so ...

Qin's Wars Of Unification
Qin's wars of unification were a series of military campaigns launched in the late 3rd century BC by the Qin state against the other six major Chinese states — Han, Zhao, Yan, Wei, Chu and Qi. Between 247 BC and 221 BC, Qin had emerged as one of the most powerful of the Seven Warring States in China. In 230 BC, Ying Zheng, the King of Qin, unleashed the final campaigns of the Warring States period, setting out to conquer the remaining states one by one. Following the fall of Qi in 221 BC, China was unified under Qin control. Ying Zheng declared himself "Qin Shi Huang" (meaning "First Emperor of Qin") and established the Qin dynasty, becoming the first sovereign ruler of a unified China. Background Rise of Qin and early conquests Over the course of the Warring States period, the Qin state had evolved to become the most powerful of the seven major states in China, particularly after Shang Yang's reforms in the mid 4th century BC. The other six states would repeate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
