We have reached a point in time where the antediluvian ways have either been completely forgotten or are simply ignored for loss of necessity. This fast progressing world owes everything to the researchers and innovators responsible for the ever changing paradigm of technology. My capability as an engineer, however, to be truly able to understand how the various design aspects behind each innovation, helping me ponder over the numerous ways in which it can be implemented for technological betterment
Tool wear is a problem in machining titanium alloy, so it is of great importance to find out the wear mechanism of cutting tools in order to improve the cutting tool life time. The mechanism controlling the wear of cemented carbide and influence of cutting parameters on different wear modes in machining Ti6Al4V has been investigated in this paper. Diffusion and chemical wear at high cutting speed and feed rate and attrition in low speed and feed rate is suggested to be the dominant wear mechanism
Tungsten The chemical element tungsten, atomic number 74, is listed as a transition metal in group VIB on the Periodic Table of Elements. Tungsten was formerly known by the Germanic name Wolfram, after the tungsten mineral wolframite, hence its chemical symbol W. The name tungsten was derived from the Swedish words tung and sten, meaning heavy stone, because of its high density. Discovery of the element is credited to Spanish brothers Fausto Jermin and nobleman Juan Jose de Elhuyar in the early
Tungsten, also known as wolfram is an element that in sedwin means heavy stone. Tungsten is a heavy stone that is used in filaments in incandescent light bulbs, it is also used in electric contacts and arc-welding electrodes.Tungsten is more resistant to fracturing than diamond and is much harder than steel.It is the refractory metals unique properties - its strength and ability to withstand high temperatures - that make it ideal for many commercial and industrial applications. Tungsten has the highest
When many people think about the element Tungsten, one common visual tends to come to mind; a light bulb. Although most know Tungsten for being used in the light bulb, it has many other uses as well that aren’t as commonly known. Tungsten was first discovered by two brothers in Spain during 1783. The brothers were named Juan Jose and Fausto de Elhuyar, and they discovered Tungsten while working one day. They were the first people whom discovered that Tungsten had the ability to become an element, so
In “Uncle Tungsten: Memories of a Chemical Boyhood” by Oliver Sacks, it is validly classified as an autobiography that is based on the memoirs on Oliver Sacks’ childhood in relation to his learning experience in the scientific topic of chemistry. The reason why I chose this book is because of the fact that the book is about a relatable main character, Oliver Sacks in his early years, and the interesting idea of learning about the out-of-school curriculum of a unique youngster who took an interest
Following are the points, where the company contradicted their actions with CSR policies: • Merger with Union Carbide • Doesn’t take any action towards environment clearance at accident site • Doesn’t take any concern towards Social welfare which was hurt due to this tragedy • Products and process Manufacturing forbidden toxic chemical If a company agrees with
In the year 1919, on January 15th, Boston experienced a strange disaster. This said disaster is now known as the Boston Molasses Flood. The disaster occurred when an above-ground tank filled with 26 million pounds of molasses burst and unleashed a wave of molasses from eight to fifty feet high and moving at 35 miles per hour killed people and destroyed buildings in the surrounding neighborhood. After the wave of molasses had slowed down, it settled at two to three feet in depth. Acting like quicksand
strategy, they were divested. Dow Chemicals has evidenced this by selling off more than $10 billion in business assets, while at the same time adding $10 billion in new business that support their new strategy, and the strategic addition of the Union Carbide Company. To develop Dow Chemicals new strategy, which is to say to develop a competitive advantage within their selected market, Dow Chemical appears to have thoroughly examined their role in the macroenvironment, which also encompasses the political/legal
sensation, excruciating pain in your lungs that makes it difficult for you to breathe and with no idea what has caused this effect. This was the feeling experienced by over 200, 000 people in Bhopal, India on Dec 3rd, 1984. A pesticide plant run by Union Carbide Corporation, an American company, experienced a gas leak from tanks containing Methyl Isocyanate (MIC). Methyl Isocyanate reacted with water producing toxic gases that spread out towards human settlements causing devastating effects. This is merely
magazine & news television channel) and covered the World’s Worst Industrial Disaster, The Bhopal Gas Tragedy. The picture shown above is captured by Raghu Rai and invades our mind with feart. This gas tragedy occurred in Bhopal’s multinational Union Carbide Corporation's pesticide formulation plant. Around 40 tons menthyl-iso-cyanate gas leaked on 2nd December, 1984 causing instantaneous deaths of more than 20,000 people over the two weeks. Nearly half of the Bhopal’s then populations were severely affected
71 percent of the people that were at The Station Nightclub Fire, which occurred in West Warwick Rhode Island on February 20, 2003, that either died or was injured. This paper will look at the contributing factors in this shocking number as it pertains to fire prevention. When breaking down a case study, this case being The Station Nightclub Fire, there are three main factors you must look at. Those factors are fire behavior, human behavior, and building behavior. How the fire started and what
Microelectromechanical Systems (MEMS) are systems that are designed on a micro metre scale and have become more popular as the demand for devices to get smaller has increased. The main uses of these systems are for sensors, such as accelerometers and gyroscopes and other such devices like microscopy and inkjet nozzles for example. There are many materials that can be used for MEMS as the cost of the material is almost eradicated due to the micro size of the systems being produced. This brings materials
19841, massive amounts of methyl isocyanate gas (500 times more poisonous than cyanide) leaked from a pesticide plant in Bhopal, India, immediately killing at least 2,000 people1 and causing significant illness and premature death to many more. Union Carbide Corporation “UCC” immediately tried to distance itself from legal responsibility, in what would become the worst industrial accident in history at that time. Eventually it reached a settlement with the Indian Government and paid $470 million2 in compensation
“collect bodies from the street.” This tragic incident exposed more than half a million people to a toxic gas that was being manufactured at a chemical plant near the city. The plant was a part of Union Carbide, a company that manufactures many chemicals, both dangerous and safe. Many people wanted Union Carbide to be held liable for the damages, while others believed that it was not the company’s
Have you ever wanted to mess with metal and fire? Have your coats been scattered around your house? Have you also had family or friends over and had nowhere to hang their coats. When welding safety is first and having safety equipment is required, once that is all done it is time to grab the material and prep it, then the final step is to build the hall-tree. Knowing how to build a hall-tree will organize your coats and make your life simpler. When starting to weld the first thing that should pop
A welding helmet, commonly known as a “hood,” is one of the maximum crucial portions of personal shielding system that a welder must have. A good enough helmet protects the eyes and skin now not best from great sparks, but additionally from doubtlessly imaginative and prescient-adverse ultraviolet and infrared rays emitted with the aid of the arc. As one of the maximum seen pieces of protection attire, a welding helmet also gives wearers a possibility to feature a chunk of personal aptitude to their
Tomorrows Welders Thomas Jefferson said, “I find that the harder I work, the less I call it work”. I have often found myself in situations where I needed to fix something but could not because it is metal. I believe this might be why I began to show interest in welding. There is great satisfaction in being able to create or fix a metal object on your own. As a Certified Welder, I will be able to combine my hardworking drive with my personal interest in metal working to be a successful welder. This
