The object of ball bearings (and roller bearings) is the substitution of pure rolling motion for plain sliding friction. <br> <br>Ball Bearings rely on the rolling motion of hardened steel balls to absorb loads. This rolling motion produces far less friction than the sliding motion. These steel balls are held in circular rows between an outer and inner ring‚ which have raceways‚ or slots‚ grooved into them to guide the balls. Ball bearings are available in both filling-slot and no filling-slot types

From the thousand yard stare to a well kept hair cut‚ military bearing is prevalent in every facet of military life‚ though military bearing is much deeper than just appearances; it is the cornerstone of any military career. Military bearing encompasses every facet of life in the military and can be applied to any situation. Military bearing itself is gleaned from several places such as‚ the articles of the UCMJ‚ The eleven general orders of a sentry‚ as well as our own Sailors Creed. From these

Introduction: An oxygen sensor‚ or lambda sensor‚ is an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analyzed. It was developed by Robert Bosch GmbH during the late 1960s under supervision by Dr. Günter Bauman. The original sensing element is made with a thimble-shaped zirconia ceramic coated on both the exhaust and reference sides with a thin layer of platinum and comes in both heated and unheated forms. The most common application is to measure the

IntroductionA dehydration reaction of an alcohol results in an alkene. This type of reaction requires an alcohol‚ an acid catalyst and heat. Generally strong concentrated acids‚ like sulfuric acid and phosphoric acid‚ are used as the acid catalyst.The acid catalyst protonates the alcohol‚ to make a much better leaving group. Weakest bases make the best leaving groups‚ so once the alcohol is protonated the leaving group leaves and produces in a carbocation and water. In order to form the double bond

IONIC COMPOUNDS In chemistry‚ an ionic compound is a chemical compound in which ions are held together in a lattice structure by ionic bonds. Usually‚ the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion. Ions in ionic compounds are held together by the electrostatic forcesbetween oppositely charged bodies. Ionic compounds have high melting and boiling points‚ and they are hard and very brittle. Ions can be single atoms‚ as the sodium and chlorine in

Estimating Formal Lab Report Introduction: Today scientists put acquired data into a form of a graph. This said graph is designed to help make predictions and furthermore‚ study and understand the experiment and its contents at hand. The Graphing and Estimating lab involves just that. The lab is designed to collect data from several tests involving burn time of a candle. Oxygen‚ O2‚ is a kind of gas. A lot of the air we breathe as human beings is oxygen. Which is good since we need oxygen to

Cleveland‚ OH. November 30‚ 2012 Summary The purpose of this report is to determine why we should lease computer equipment as opposed to purchasing computer equipment. Leasing computers can save this organization revenue by not having to have an on-site IT Department for any hardware or software issues that develop. Any technological advances that develop can be upgraded to stay current with technology. This report will also look at the total cost of ownership as compared to leasing computer
