HYDROGEN
HYDROGEN Hydrogen, symbol H, is reactive, colorless, odorless, and tasteless gaseous element. The atomic number of hydrogen is 1. The element is usually classed in group 1 of the periodic table. Hydrogen was confused with other gases until the a British chemist demonstrated in 1766 that it was evolved by the action of sulfuric acid on metals and also showed at a later date that it was an independent substance that combined with oxygen to form water. The British chemist Joseph Priestley named th...

What Is A Robot
What is A Robot WHAT IS A ROBOT The term robot comes from the Czechoslovakian wordfor forced labor, invented by Karel Capek. Karel Capek used robots in his plays and had them look and behave like people. Today, the word robot is harder to define because of new designs and technology. The third edition of Websters's New International Dictionary defines a robot as a machine in the form of a human being that performs the mechanical functions of a human being. However, today's robot makers are...

Helium And Janssen
Helium And Janssen A French astronomer, Pierre-Jules-C?sar Janssen (1824-1907), first obtained evidence for the existence of helium during the solar eclipse of 1868 in India when he detected a new yellow line (587.49 nm) in the solar spectrum very close to the yellow sodium D-line. It was not possible to produce this line in the laboratory. Sir Norman Lockyer (1836-1920), an English astronomer, recognised that no known element at that time gave this line and named the element helium for the sun...

Organic Chemistry
Organic Chemistry Organic compounds are covalently bonded compounds containing carbon, excluding carbonates and oxides. Carbon atoms are unique because of their ability to bond by catenation, which is forming long chains and rings from the covalent binding of an element to itself. Besides bonding with itself, carbon atoms are able to bind to elements with similar electronegativities. Organic compounds consist of carbon and these other elements. Hydrocarbons are the simplest organic compounds, co...

Pollution
Pollution very efficiently transmitted through the generally stiff, metallic and therefore resonant structures. One common way of overcoming the considerable nuisance this can cause for the occupants is by absorbing the vibration and actually converting it to heat using viscoelastic polymer materials, typically based on polyurethanes or acrylics. Over the past 20 years, Swedish Acoustic Products -- Swedac -- has built a track record in overcoming noise and vibration problems using this basic tec...

Robots
Robots ROBOTS Webster's New World Dictionary defines a robot as any anthropomorphic mechanical being built to do routine manual work for human beings. This term was popularized by the Czech dramatist Karel Capek (1890-1938) in his 1921 play Russum's Universal Robots (R.U.R.). The term has been used in fiction to describe self-controlling machines that resemble human beings. This concept has been the basis of stories starting centuries before, but has become popular due to the writings of science...

Oxygen
Oxygen Oxygen is one of the 92 known elements. An element is a substance that cannot be decomposed into a simpler substance by any simple means. Each of the 92 naturally occurring elements are therefore one of the fundamental materials from which everything in the Universe is made. The History of Oxygen On August 1,1774, Joseph Priestley examined the effect of intense heat on mercuric oxide. He noted that an air or gas was readily expelled from the specimen. To his surprise a candle burned in th...

casting
Casting It is a manufacturing process by which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process. Casting materials are usually metals or various cold setting materials that cure after mixing two or more components together; examples are epoxy, concrete, plaster and clay. Casting is most often used for...

Its The Drive Cone Cavity Engineering Essay
Its The Drive Cone Cavity Engineering Essay The drive cone cavity is one of the hottest un-cooled components in the engine. Operating around 900k at 10,000 rpm, the material used in making the drive cone is operating at edge of its safe working temperature changes at these high temperatures. A 10 K rise in shaft temperature can reduce the life of the shaft. The temperature must therefore be predicted to within 10 K or better to guarantee accurate stress predictions. It the thermal model cannot g...

Theory of constraints
Theory of constraints The Theory of Constraints is a methodology for identifying the most important limiting factor (i.e. constraint) that stands in the way of achieving a goal and then systematically improving that constraint until it is no longer the limiting factor. In manufacturing, the constraint is often referred to as a bottleneck. The core concept of the Theory of Constraints is that every process has a single constraint and that total process throughput can only be improved when the co...
