The assigned material for this week's article summary assignment is titled "Metal polishing: Do this, not that". The article is authored by CTD Mike, and was published on 06 Oct 11. The article appears on the cheaperthandirt.com website, and may be sourced at: http://blog.cheaperthandirt.com/metal-polishing-this/. The article begins with the assumption you have a task to perform that involves removing metal. Should I use the Dremel rotary tool? Stones? If you want to make sure you don't jack up…

Since I had such huge success with my salt water powered car, I decided to put a spin on the sale of my products. I decided to make something like a car, but also spice it up a little bit. What I did was I made it inflatable and able to run on water. With that being said it was a fully functional car, but if you ever wanted to take it across the water to maybe shorten a trip or just for pure enjoyment then you could do so. I didn’t really need this product to keep my car company at the top.…

There are many opportunities to reduce one’s consumption and to better manage one’s waste by taking advantage of the establishments in Ottawa designed for such a purpose. Bulk Barn is an excellent store for those seeking to reduce, or better yet, eliminate, all plastic products from their life. One need only bring a reusable container to a Bulk Barn location, and then fill it with a large variety of grains, flours, spices and dried beans, all while foregoing plastic packaging. Not only is…

As you consume bottled water, you are also taking the risk to get cancer and various reproductive damages. Human body need water, it is our biological needs. However, people choose to drink bottled water is just for them to meet their secondary needs. If you could choose between bottled water and drink water fresh out from the tap, I believe you would go for bottled water. No doubt that our body needs water to survive. In US, most of the people have the access to tap water, but there is a large…

3. Occurrence of the Accident/Incident The freighter SS Fort Stinkine which is a cargo ship arrived at Bombay on Friday, 12 April, 1944 No one in the Dock area was aware about the dangerous cargo which she was carrying. Normally a red flag has to be flagged to indicate the explosive but avoided due to war time.Emergency A certificate has been issued by the Dock yard higher officials to unload it in priority basis. Unloading of the ship commenced immediately. However while unloading the lube…

This lab module covers the subjects of optical spectroscopy of gas discharges and bond stiffness of materials. Optical spectroscopy can be observed using different types of equipment, such as, a spectrometer, a light collecting fiber, and tubes of certain types of gas (He, H2O, H2 and O2). The data collected displays the peak wavelengths for each of the gases, which can be used to determine the energy released when the electrons change energy levels. Overall, it was interesting to see how…

tonnes finish in oceans (Parker 2015). Only 15% of the total plastic production is recycled. The rest of the waste ends up in oceans, beaches, rivers and streets. In fact, the so-called Pacific Garbage Patch is constituted entirely by remnants of this material. Plastics are produced from fossil fuels, a source of clean energy, which causes emissions of greenhouse gases, and non-renewable because in a few years its reserves will be exhausted. But a solution to the problem of plastic waste could…

building is going to take place. The subsoil has to be able to carry these loads. The primary loads are natural loads, forces due to gravity. That are as follows; Dead load This is the permanent elements of the structure, a consistent load as the materials of the house will always be there. The architect can calculate this load. The objects involved are; • Floors • Walls • Ceilings • Slabs • Columns etc Imposed or live load This is the load of all the people in the building, for example in a…

due to various reasons: Uncertainties in loading or environment Defects in material Inadequacy in design Deficiency in construction or maintenance The strength of materials can be increased significantly. But sometimes this comes at the cost of reduced ductility of the material. For example, strength of steel can be increased by manipulating the microstructure. But this increases the brittleness of the material. Thus, a member can fail catastrophically due to crack formation and…

strengths that materials can be tested on: Comprehensive strength and Ultimate Tensile strength. Ultimate Tensile strength is measured by how much stress can a material withstand, while being stretched or pulled apart before breaking, while comprehensive strength is how much van the material resists while being pushed in (together). There is also a Yield Strength- the point at which the material starts to slowly break and cannot come back to it’s shape. Before the yield point of a material, it…
