Mechanical engineering is a discipline of engineering that applies the principles of engineering, physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems. It is the branch of engineering that involves the production and usage of heat and mechanical power for the design, production, and operation of machines and tools. It is one of the oldest and broadest engineering disciplines.
The engineering field requires an understanding of core concepts including mechanics, kinematics, thermodynamics, materials science, structural analysis, and electricity. Mechanical engineers use these core principles along with tools like computer-aided engineering, and product lifecycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices, weapons, and others.
Military technology is the collection of equipment, vehicles, structures and communication systems that are designed for use in warfare. It comprises the kinds of technology that are distinctly military in nature and not civilian in application, usually because they are impractical in civilian application, have no legal civilian usage, or are dangerous to use without appropriate military training.
It is common for military technology to have been researched and developed by scientists and engineers specifically for use in battle by the armed forces. Many new technologies came as a result of the military funding of science. Weapons engineering is the design, development, testing and lifecycle management of military weapons and systems. It draws on the knowledge of several traditional engineering disciplines, including mechanical engineering, electrical engineering, mechatronics, electro-optics, aerospace engineering, materials engineering, and chemical engineering.
An assault rifle is a selective fire (selective between semi-automatic, automatic and/or burst fire) rifle that uses an intermediate cartridge and a detachable magazine. Assault rifles are the standard service rifles in most modern armies. Note the difference between the assault rifle and the battle rifle. Assault rifles use smaller cartridges and are used at closer ranges than battle rifles. The larger sized rifle cartridges used in battle rifles make fully automatic fire more difficult. Fully automatic fire refers to an ability for a rifle to fire continuously while the trigger is pressed; "burst-capable" fire refers to an ability of a rifle to fire a small yet fixed multiple number of rounds with but one press of the trigger; in contrast, semi-automatic refers to an ability to fire one round per press of a trigger. The presence of selective fire modes on assault rifles permits more efficient use of rounds to be fired for specific needs, versus having a single mode of operation, such as fully automatic, thereby conserving ammunition while maximizing on-target accuracy and effectiveness.
Examples of assault rifles include the StG 44, AK-47, M16 rifle, QBZ-95, FAMAS, Heckler & Koch G36, and Enfield SA80.
A semi-automatic rifle is a rifle that fires a single round each time the trigger is pulled, uses gas, blowforward, blowback, or recoil to eject the spent cartridge after the round has traveled down the barrel, chambers a new cartridge from its magazine, and resets the action; enabling another round to be fired once the trigger is depressed again.
The self-loading design was a successor to earlier rifles that required manual-cycling of the weapon after each shot, such as the bolt-action rifle or repeating rifles, which required the operator to manual cycle the action before each shot. The ability to automatically load the next round allowed for an increase in the rounds per minute the operator could fire.
