Trusses have a high strength to weight ratio and consequently are used in many structures, from bridges, to roof supports, to space stations.The Pros of a Truss Bridge 1. They might be light, but they are also strong. Truss bridges utilize the materials that are needed to create them very effectively. This makes them very economical to build, but doesn’t compromise on the ground of the bridge. Because it uses small timbers, the…

10 degrees to facilitate draining of water and snow. The concept of flat roofs was introduced centuries ago. There are various kinds of roofing available in the market today and you have to choose the type of roofing keeping in mind the kind of building and its geographical location. Flat roofing is one such kind that you might want to go for. One of…

A Few Options To Consider When Buying A New Asphalt Shingle Roof When it's time to put a new roof on your home, you'll likely go with asphalt shingles, especially if you currently have asphalt now. That's because this roofing material is less expensive and therefore more popular than other types of roofing. If you take a look around your neighborhood, your likely to see most of the homes have asphalt shingles no matter what climate you live in. However, just because you choose asphalt, it…

Polyethylene terephthalate, most commonly known as plastic, is a material consisting of a wide range of synthetic and/or semi-synthetic organics that are malleable/ductile and can be molded into many solid objects. Plastics are typically made of organic polymers (chains of carbon or chains of carbon that have been bonded to other elements such as oxygen, nitrogen or sulfur) having high molecular masses, but often contain other substances. Usually being synthetic, and most commonly made from…

They have many advantages when considered for industrial and machinery and lubrication purpose. Vegetable oil can have excellent lubricity and lubrication properties over synthetic oil. In many applications like for tractor transmission, friction material need to be added to reduce clutch slippage [8]. Lubricants need to possess some lubrication properties which give good machining performance. Vegetable oil have very high viscosity index (VI). For example 223 for soya bean oil versus 90-100 for…

and experiment 2 exploits this to help understand structure property relationships. The knowledge gained here directly applies to the world as applications of the materials becomes apparent as the properties are explored. Copper There are a plethora of modern technological uses of copper. It can be used in electrical wiring, building sturdy structures, transportation and sculptures. Based off data gathered from the internet [1]. Copper is used 65% of the time for electrical infrastructure, 25%…

Engineering with respect to the work that preceded it, and how this research should be developed further in the future.” Nowadays, cellular materials are well-known in the world, however, the relationship between dynamic load and the deformation of the lattice structure is less well-studied. Actually, lattice structures can help engineer to produce macro-scale material properties more easier. The research “Energy absorption in lattice structures in dynamics” was focusing on characterising the…

4.1 First Side by Side Geometry The first model shown in figure 3 was for twin tunnels already constructed at a centre to centre spacing of 3D. This model helped to identify the influence of construction sequence on surface and subsurface ground displacement upon excavating the first and second tunnels underneath the existing twin tunnels. Figure 3: First Side by Side twin tunnels 4.1.1 Surface Displacements The surface displacements at distances of 4.75m, 7.125m, 9.5m and 11.875m from the…

3. Uses of Building information Modeling (BIM) BIM is a 3-D model process used in the engineering, architecture and construction with tools to manage the project effectively in planning, designing, constructing and operational phase. At every stage of project development, BIM plays a vital role, in planning BIM is used for cost estimation; phase planning, site analysis and programming. In the design phase, BIM used for structural analysis, lightning analysis, mechanical analysis, LEED evaluation…

thing to learn if you want to be a bomb maker, I’m going to research the history about the bomb and explosion and then I’m going to research the step and the material about the bomb and how to make a bomb easy to carry and make the bomb not easy to be founded. If you want it to explosion, you have to have to material of that, so the material of that have a lot of kind such as: Octanitrocubane HMX Tetry Trinitrotoluene and the most famous one and the most useful one was C-4 explosive. And I…
