Riveting Machine
A riveting machine is used to automatically set (squeeze) rivets in order to join materials together. The riveting machine offers greater consistency, productivity, and lower cost when compared to manual riveting.Parker, Dana T. ''Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II,'' p. 30, Cypress, CA, 2013. ISBN 978-0-9897906- 0-4. Types Automatic feed riveting machines include a hopper and feed track which automatically delivers and presents the rivet to the setting tools which overcomes the need for the operator to position the rivet. The downward force required to deform the rivet with an automatic riveting machine is created by a motor and flywheel combination, pneumatic cylinder, or hydraulic cylinder. Manual feed riveting machines usually have a mechanical lever to deliver the setting force from a foot pedal or hand lever. Riveting machines can be subdivided into two broad groups — impact riveting machines and orbital (or radial) rive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydraulic Tools
Hydraulics () is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and they cover concepts such as pipe flow, dam design, fluidics, and fluid control circuitry. The principles of hydraulics are in use naturally in the human body within the vascular system and erectile tissue. ''Free surface hydraulics'' is the branch of hydraulics dealing with free surface flow, such as occurring in rivers, canals, lakes, estuaries, and seas. Its sub-f ...

Ring Binder
Ring binders (loose leaf binders, looseleaf binders, or sometimes called files in United Kingdom, Britain) are large folders that contain file folders or hole punched papers (called Loose leaf, loose leaves). These binders come in various sizes and can accommodate an array of paper sizes. These are held in the binder by circular or D-shaped retainers, onto which the contents are threaded. In North America, the rings themselves come in a variety of sizes, including , though other sizes are also available. The rings may be secured by lever arch mechanisms or other securing systems. The binders themselves are typically made from plastic with metal rings. Early designs were patented during the late 19th century. History American Henry Tillinghast Sisson invented a "new and useful improvement in portfolios and paper files" he called a "temporary binder." It used a spring inside a tube to hold papers securely. He receivepatent no. 23506on April 5, 1859. German Friedrich Soennecken in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Component
An electronic component is any basic discrete electronic device or physical entity part of an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form and are not to be confused with electrical elements, which are conceptual abstractions representing idealized electronic components and elements. A datasheet for an electronic component is a technical document that provides detailed information about the component's specifications, characteristics, and performance. Discrete circuits are made of individual electronic components that only perform one function each as packaged, which are known as discrete components, although strictly the term discrete component refers to such a component with semiconductor material such as individual transistors. Electronic components have a number of electrical terminals or leads. These leads connect to other electrical components, often over wire, ...

Door Furniture
Door furniture (British English, British and Australian English) or door hardware (North American English) refers to any of the items that are attached to a door or a Drawer (furniture), drawer to enhance its functionality or appearance. Design of door furniture is an issue to disability, disabled persons who might have difficulty opening or using some kinds of door, and to specialists in interior design as well as those usability professionals which often take their didactic examples from door furniture design and use. Items of door furniture fall into several categories, described below. Hinges A hinge is a component that attaches one edge of a door to the frame, while allowing the other edge to swing from it. It usually consists of a pair of plates, each with a set of open cylindrical rings (the knuckles) attached to them. The knuckles of the two plates are offset from each other and mesh together. A hinge pin is then placed through the two sets of knuckles and usually fix ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Skin
The skin of an aircraft is the outer surface which covers much of its wings and fuselage. The most commonly used materials are aluminum and aluminium alloys with other metals, including zinc, magnesium and copper.

Aerospace
Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial, and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, maintain, and repair both aircraft and spacecraft. The border between space and the atmosphere has been proposed as above the ground according to the physical explanation that the air density is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. This border has been called the Kármán line. Overview In most industrial countries, the aerospace industry is a co-operation of the public and private sectors. For example, several states have a civilian space program funded by the government, such as NASA, National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space A ...

Trade-off
A trade-off (or tradeoff) is a situational decision that involves diminishing or losing on quality, quantity, or property of a set or design in return for gains in other aspects. In simple terms, a tradeoff is where one thing increases, and another must decrease. Tradeoffs stem from limitations of many origins, including simple physics – for instance, only a certain volume of objects can fit into a given space, so a full container must remove some items in order to accept any more, and vessels can carry a few large items or multiple small items. Tradeoffs also commonly refer to different configurations of a single item, such as the tuning of strings on a guitar to enable different notes to be played, as well as an allocation of time and attention towards different tasks. The concept of a tradeoff suggests a tactical or strategic choice made with full comprehension of the advantages and disadvantages of each setup. An economic example is the decision to invest in stocks, which ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Explanation Graphic
An explanation is a set of statements usually constructed to describe a set of facts that clarifies the causes, context, and consequences of those facts. It may establish rules or laws, and clarifies the existing rules or laws in relation to any objects or phenomena examined. In philosophy, an explanation is a set of statements which render understandable the existence or occurrence of an object, event, or state of affairs. Among its most common forms are: * Causal explanation * Deductive-nomological explanation, involves subsuming the explanandum under a generalization from which it may be derived in a deductive argument. For example, “All gases expand when heated; this gas was heated; therefore, this gas expanded". * Statistical explanation, involves subsuming the explanandum under a generalization that gives it inductive support. For example, “Most people who use tobacco contract cancer; this person used tobacco; therefore, this person contracted cancer”. Explanations ...
