3 SHORE DUROMETER HARDNESS STRENGTH Hardness was defined as materials resisting property to prevent permanent indentation. Durometer is a measure of hardness in polymers, fibre and rubbers where it measures the indentation depth in the material. According to ASTM D2240 tests were conducted on specimen using Durometer in the room temperature [5]. The test is done on the surface by supplying load and measuring the indentation. The material under test must be a minimum of 6.4 mm thickness. It was…

Linear Horn: The linear horn, also known as the straight-sided horn, is a cone-shaped shell with no curvature, it is the oldest and simplest design. The pressure change through the horn is linear as a sound wave moves through it, so there is no distortion of the sound. The gradual change in the cross-sectional area of the horn decreases distortion and provides a good phase response due to compressed air in the throat. Devices intended to reproduce human voices, such as the megaphone, are…

Titanium is a low-density element (has 60% density of steel), that be able to be highly modified by alloying and distortion processing. Titanium is non magnetic, non toxic and has good heat transfer properties. Titanium and its alloys have melting points advanced those of steels, but maximum useful temperatures for structural applications usually range from 425-540C°. Titanium has good resistance to attack by most mineral acids and chlorides [ASM]. The combination of high strength, stiffness,…

interfacial attachment is the use of bioactive materials (type3). The concept of bioactive materials is intermediate between resorbable and bioinert. Certain compositions of glasses, ceramics, glass-ceramics, and composites have been shown to bond to bone. These materials are also called bioactive ceramics. Some, even more specialized compositions of bioactive glasses, will bond to soft tissues as well as bone. A common characteristic of such bioactive materials is a modification of the surface…

4.TAGUCHI ANALYSIS FOR THE EXPERIMENTAL RESULTS To examine the 100Cr6 bearing steel through DCT, and to identify the optimum parameter condition of the DCT process, the prediction of the Taguchi analysis is used. The Taguchi analysis and ANOVA, gives the optimized parameter setting and the most influential factor of the DCT process respectively. The quality performance of the deep cryo-treated 100Cr6 steel samples based on the L9 OA was evaluated by conducting the reciprocatory wear tests.…

the extraordinary range of properties. Polymers are among the most widely used and important type of materials today. Polymers have been with us from the beginning of time; they form the very basis (building blocks) of life. Animals, plants all classes of living organisms are composed of polymers. Polymers can be classified according to origin: synthetic macromolecules made of fossil raw materials (such as petrochemicals produced by cracking or refining of crude oil), or naturally occurring…

Plastic Bottles Are Just Big Trouble “50 billion plastic bottles are used each year in America, that’s enough to wrap around the world 190 times,” (Leithman). Even though plastic bottles are popular now, when they were first created in 1947, they were very expensive and not many people bought them. However, in 1960, high-density polyethylene was made and introduced to the public. As the demand for plastic bottles escalated, consumers produced more plastic bottles for cheap, while selling the…

CHARACTERISTICS Often materials are subject to forces (loads) when they are used. The mooring lines have to withstand the loads acting on the moored structure in addition to loads acting directly on the mooring components (Bjørnsen 2014). Mechanical engineers calculate those forces and material scientists how materials deform (elongate, compress, and twist) or break as a function of applied load, time, temperature, and other conditions (Virginia.edu 2013). 1.4.1. Tensile Load The mooring line…

research that I have found there are three main useful ideas on how to limit the use and waste of plastic water bottles and they are: reusing the bottles at home, recycling with a reputable recycler, and using refillable bottles when able. Using old material at home to create new goods has become a growing part of the US society mainly because of sites like Pinterest that show creative ways to reuse things that would normally be thrown away. This is the same even with plastic bottles, such as…

Paragraph 1 The crystal chemical relationship between quartz (SiO2) and FePO4 can be studied by putting them under a temperature range of 294K to 1073K in an attempt to study the evolution of their structures. In doing so, we would able to examine the other quartz homeotypes that emerge during high temperatures and known to show a-b transitions. This study of quartz homeotypes were essential because the new information that was gathered would aid greatly in the creation of new products and more…
