Material used in engine block casting In order to meet the above functional requirements the material used for manufacturing the product should contain many properties. They are‚ the material should contain high strength‚ modulus of elasticity‚ wear resistance‚ ability to withstand vibrations‚ and corrosion resistance. High strength is mostly concerned in diesel engines because of their high compression ratios compared with petrol engines. In diesel engine its compression ratios are normally 17:1

1. TEN GREAT LOW-COST TEACHING TOOLS Educational material created by Prof. Alejandra Masís Artavia‚ 2011. 2. INTRODUCTION This presentation’s aim is to provide teachers with ten low-cost teaching tools. Moreover‚ it seeks to explain the importance of using these tools and how they can be used in several ways‚ as Kevin McCaughey states in his article. 3. Tool 1: Scissors (and scratch paper)Importance of using scissors: they transform a single piece of scratch paper into 10‚ 20‚ and even 50 paper

Engineering Materials Week 7 10.4 (a) For the solidification of nickel‚ calculate the critical radius r* and the activation free energy ∆G* if nucleation is homogeneous. Values for the latent heat of fusion and surface free energy are -2.53 X10⁹ J/m3 and 0.255 J/m2. (b) Now calculate the number of atoms found in a nucleaus of critical size. Assume a lattice parameter of 0.360 nm for solid nickel at its melting temperature. (116 unit cless/critical nucleus)(4 atoms/unit cell)=464 atoms/critical

Recycling is processing used materials into new products to prevent waste of potentially useful materials‚ reduce the consumption of fresh raw materials‚ reduce energy usage‚ reduce water and air pollution. Many kinds of glass‚ paper‚ metal‚ plastic‚ textiles and electronics can be recyclable materials. Goverments encourage their citizens to seperate their garbage and they make some rules for restaurants and supermarkets to supply recycling process. Although it is claimed that recycling is not worth

Using material from Item A and elsewhere assess sociological explanations for ethnic differences in educational achievement. As well as social class‚ ethnicity also plays an important part in educational achievement. Just as we can think of everyone as belonging to a social class‚ we can also see individuals being part of an ethnic group. Lawson and Garrod (2000) define ethnic groups as ‘people who share common history‚ customs‚ language and religion‚ and who see themselves as a distinct unit’

beret and so on. In Vietnam‚ the conical pleasant hat‚ or non la‚ serves as a very important tool used by everyone. The non la‚ translates "leaf hat‚" because it is made out of leaves and is also very light and thin. The non la is used by villagers for protection from the sun‚ and it is also used as a fan in the hot and dry weather. The non la is also a symbol of beauty because it shows the very poor‚ simple life of a Vietnamese farmer. The non la dates back to the earliest civilizations thousands of
