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.…

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…

Knee Wraps: The Benefits and Drawbacks What are knee wraps? The knee wrap is similar to the wrist wrap regarding the logic that applies to both. Knee wraps are also to an “Ace” bandage, except that they are much thicker and stronger. The elastic material that is used to make the knee wrap is the same found in wrist wraps. The allowed width for knee wraps is 8 cm (3 inches), although they can sometimes be 2.0 meter, 2.5 meters or even 3.5 meters long. Advantages of using knee wraps The primary…

Water is a natural gift given to us by nature. Some of us drink it when we are thirsty and some of us drink it when we are fully hydrated. The surprising thing is that there are some people who do not like drinking water at all. In fact, we need water to keep our health well no matter who we are. The importance of drinking water for our bodies is paramount to our health, because it makes up to 70 percent of our bodies’ weight. Drinking water regularly in daily basis is the best gift we can offer…

for Granite epoxy specimens is documented and listed in Table 5.1. Table 5.1 Compression Test results for Granite Epoxy Specimens Figure 5.1 shows the compressive strength plot of granite epoxy composite specimens without the inclusion of filler material. From the graph, it is observed that the compressive strength of the fabricated specimen’s increases up to 70% granite content and further decreases with the increase in epoxy percentage. The maximal compressive strength obtained is 112MPa for…

HARDNESS Hardness of a material is most commonly defined as the measure of its resistance to penentration by an indenter.Hardness is also measure of strength and often has the units of stress .The indenter is often fabricated from a hard material such as diamond or hardened steel.The tips of the indenters may be conical,pyramidal,or spherical in shape.The indenter tips may also be relatively small(nano-or micro-indenters) or very large(macroindenters).Since indentation tests are relatively easy…

The SEM result was also in good agreement of XRD analysis. The average particle size of CuMnRC1, CuMnRC2 and CuMnRC3 catalyst was 0.675µm, 3.127µm and 7.435µm respectively. The particles of CuMnRC1 catalyst was least agglomerated, highly porous, high surface area and uniformly distributed. The choice of different precipitant in the CuMnOx catalysts leads to the change of the surface distribution of Cu, Mn and O elements, which might be related to the CO oxidation catalytic performance of the…
