Square (tool)
A square is a tool used for marking and referencing a Right angle, 90° angle, though Miter square, mitre squares are used for 45° angles. Squares see common use in woodworking, metalworking, construction and technical drawing. Some squares incorporate a scale for measuring distances (a ruler) or for calculating angles. Terminology Many squares are made of two parts, a ''stock'' and a straight ''blade'' or ''tongue''. The stock is usually thicker than the blade, with the blade being fixed into or onto the stock. The blade typically has parallel edges. The stock is usually held against the edge of a workpiece or drawing board and the tongue is then used as a straight edge for making a mark, or as a reference to check the accuracy of an angle. History Wooden Try square, try squares have survived from Ancient Egyptian technology, Ancient Egypt and Roman technology, Ancient Rome and can be seen in art from the time. From the 18th century squares began to be manufactured in Fact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Combination Square
A combination square is a multi-purpose measuring and marking tool used in metalworking, woodworking, and stonemasonry. It is composed of a Ruler, rule and one or more interchangeable heads that can be attached to the rule. Other names for the tool include adjustable square, combo square, and sliding square. The most common head is the standard head, which is used as a Square (tool), square for marking and testing 90° and 45° angles. The other common types of head are the protractor head, and the centre finder head. Description Rule Combination square rules are made of steel and can be purchased with gradations in Metric system, metric, Imperial units, imperial, or both metric and imperial. Both faces of the rule have markings, providing four different sets of markings. This allows different sides to have different graduations (eg. 1mm or 0.5mm markings) or units (ie. metric and imperial). The rule typically comes in lengths between 150mm and 600mm or between 4 inches and 24 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bisection
In geometry, bisection is the division of something into two equal or congruent parts (having the same shape and size). Usually it involves a bisecting line, also called a ''bisector''. The most often considered types of bisectors are the ''segment bisector'', a line that passes through the midpoint of a given segment, and the ''angle bisector'', a line that passes through the apex of an angle (that divides it into two equal angles). In three-dimensional space, bisection is usually done by a bisecting plane, also called the ''bisector''. Perpendicular line segment bisector Definition *The perpendicular bisector of a line segment is a line which meets the segment at its midpoint perpendicularly. *The perpendicular bisector of a line segment AB also has the property that each of its points X is equidistant from segment AB's endpoints: (D)\quad , XA, = , XB, . The proof follows from , MA, =, MB, and Pythagoras' theorem: :, XA, ^2=, XM, ^2+, MA, ^2=, XM, ^2+, MB, ^ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dowel
The dowel is a cylindrical shape made of wood, plastic, or metal. In its original manufactured form, a dowel is long and called a ''dowel rod'', which are often cut into shorter ''dowel pins''. Dowels are commonly used as structural reinforcements in cabinet making and in numerous other applications, including: * Furniture shelf supports * Moveable game pieces (i.e. pegs) * Hangers for items such as clothing, key rings, and tools * Wheel axles in toys * Detents in gymnastics grips * Supports for tiered wedding cakes Wood dowel Manufacturing process The traditional tool for making dowels is a ''dowel plate'', an iron (or better, hardened tool steel) plate with a hole having the size of the desired dowel. To make a dowel, a piece of wood is split or whittled to a size slightly bigger than desired and then driven through the hole in the dowel plate. The sharp edges of the hole shear off the excess wood.Ivin SickelsExercises in Wood-Working American Book Company, 1889; see ...

Tradesman
A tradesperson or tradesman/tradeswoman is a skilled worker that specialises in a particular trade. Tradespeople (tradesmen/women) usually gain their skills through work experience, on-the-job training, an apprenticeship program or formal education. As opposed to a master craftsman or an artisan, a tradesperson (tradesman/tradeswoman) is not necessarily restricted to manual work. History In Victorian England, The terms "skilled worker," "craftsman," "artisan," and "tradesman" were used in senses that overlap. All describe people with specialized training in the skills needed for a particular kind of work. Some of them produced goods that they sold from their own premises (e.g. bootmakers, saddlers, hatmakers, jewelers, glassblowers); others (e.g. typesetters, bookbinders, wheelwrights) were employed to do one part of the production in a business that required a variety of skilled workers. Still others were factory hands who had become experts in some complex part of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Factory
A factory, manufacturing plant or production plant is an industrial facility, often a complex consisting of several buildings filled with machinery, where workers manufacture items or operate machines which process each item into another. They are a critical part of modern economic production, with the majority of the world's goods being created or processed within factories. Factories arose with the introduction of machinery during the Industrial Revolution, when the capital and space requirements became too great for cottage industry or workshops. Early factories that contained small amounts of machinery, such as one or two spinning mules, and fewer than a dozen workers have been called "glorified workshops". Most modern factories have large warehouses or warehouse-like facilities that contain heavy equipment used for assembly line production. Large factories tend to be located with access to multiple modes of transportation, some having rail, highway and water load ...

The Romans achieved high levels of technology in large part because they borrowed technologies from the Ancient Greece, Greeks, Etruscans, ...

Ancient Egyptian Technology
Ancient Egyptian technology describes devices and technologies invented or used in Ancient Egypt. The Egyptians invented and used many simple machines, such as the inclined plane, ramp and the lever, to aid construction processes. They used rope trusses to stiffen the beam (nautical), beam of ships. Egyptian paper, made from papyrus, and ancient Egyptian pottery, pottery were mass-produced and exported throughout the Mediterranean Basin. The wheel was used for a number of purposes, but chariots only came into use after the Second Intermediate Period. The Egyptians also played an important role in developing Mediterranean maritime history, maritime technology including ships and lighthouses.
