Abstract This report is to highlight the methods‚ results and theory relevant during an engineering experiment called “cold rolling of metals". The purpose of this report is to show how readings obtained from the set-out experiment‚ can be evaluated to determine the behavior of 3 selected materials; Brass‚ Copper and Aluminium through the process of cold rolling. The form of the materials are in small strips which are processed via cold-rolling method 4 times from their original state to evaluate

Blue Gold This is a documentary about the ever increasing water crisis in our world today; what is causing it‚ the consequences‚ and how to stop it. Ecologists everywhere began to take notice of the “desertification” of our planet and the dire consequences ahead if it is not stopped. The urgency of this issue is one that cannot be brushed off because it is not us destroying solely the planet we live on‚ but destroying our chances of survival on it. Desertification of the earth is caused

GOLD MINING AND THE ENVIRONMENT Dirty gold mining has ravaged landscapes‚ contaminated ecosystems with toxic waste and resulted in widespread water pollution. Cyanide and mercury‚ two highly toxic substances‚ have been released freely into the environment as a result of dirty gold mining. TOXIC WASTE Toxic waste is a devastating consequence of dirty gold mining practices. Cyanide heap leaching is the cheapest way to extract gold and as a result‚ is commonly used around the world. The process leaves

Density of Metals Lab 1. Purpose The purpose of this lab was answered in 4 questions‚ and their answers are here shown. The density of the metals we used were 5g/cm3. The density of a metal piece does not depend on its size‚ it depends on the total mass and total volume. The most accurate way of determining density is dividing mass by volume. You can’t identify metals by their density. It can help you narrow the options down‚ but you can’t identify a metal by using only its density. 2. Question

Metal detectors in schools pose more of a threat than a sense of security. Every student carries metal of some form on them. Pens‚ pencils‚ notebooks and other school supplies all contain metals. If we try to make schools “safer” by placing metal detectors in the entrance and exit of every school building. With many school shootings and stabbings‚ media and parents have proposed new safety measures. Placing metal detectors and spending extra time on safety management takes time away from class and

renovation‚ most people don;t think about it much before it is time to get a new roof. However‚ there are many great alternatives to asphalt shingles‚ and metal roofing is an option that stands out. Of course‚ when imagining a metal roof‚ the first thing that comes to the many people’s minds is a warehouse or other commercial structure. Metal roofing has come a long way and is so much more fashionable that its reputation‚ and is even being used on high-end mansions.

DRAWING AND ITS PROCESSES Drawing is a metalworking process which uses tensile forces to stretch metal. It is broken up into two types: sheet metal drawing and wire‚ bar‚ and tube drawing. The specific definition for sheet metal drawing is that it involves plastic deformation over a curved axis. For wire‚ bar‚ and tube drawing the starting stock is drawn through a die to reduce its diameter and increase its length. Drawing is usually done at room temperature‚ thus classified a cold working process

I.Case Analysis Overview Cumberland Metal Industries (CMI) is one of the largest metal manufacturers in the world. The company evolved from selling metal as a finished product to one that used it as a raw material‚ increasing sales from $250‚000 in 1963 to over $18‚500‚000 in 1979. Currently‚ CMI relies heavily on SlipSeal‚ which is used as a high-temperature sealant in automobiles. Although CMI dominates the market for this product‚ corporate sales figures decreased over the last year. As a
