Metals

1.         The Purpose Of The screen: - 44mm Galvanised - 57mm aluminium - 67mm sloven - 7mm Galvanised ·         I go forth be measuring the deflection of the 4 types of materials and beholding how oft it would hold on it with incubuss. And alike I bequeath be scuffing, piling, creasing, scratching, indentation, and seeing the alterations in the influence and flexibility. ·         The reason why we be preforming the test is to learn the strength of the materials and toughness of the materials. 2.The Materials apply In Testing: -44mm Galvanised -aluminum - pig bed -7mm Galvanised Galvanised Steel Rusts easily in break dance airmanship and gradu every(prenominal)y wears a manner, or eats. To prevent this corrosion, it whitethorn be c everyplace with a layer of another admixture that does not eat up. surface is champion such metal. finis marque with zinc is called Galvanising. It is utilise for coating su ch things as wire-netting, buckets, storage tanks, and structures. Steel writing of ass also be Galvanised in other ways. One way is to spray the steel with molten zinc. Another way is to vex it in a container with zinc ?dust. Copper Copper is one of our most multipurpose metals. It is also one of the few metals that atomic number 50 be found in metal form in nature. But most Copper comes from ores mined deep in the ground. Copper has an Attractive reddish-orange colour. It can easily be thrashing into thin sheets and complicated shapes and drawn into wire. It also does not wipe bug forth (wear away) quickly when exposed to the air. Aluminium Aluminium is a queerly valuable metal because it is so light. It is much lighter than steel, and goal to of its alloys atomic number 18 as strong as steel. Aluminium and its alloys are hence widely used in railway carriages, ships, and aeroplanes where agility and strength are needed. Also Aluminium does not corrode (wear awa y) when exposed to the air. 3.A Descriptio! n Of The Test cognitive operation: ·         My partner Rikki and I got all of our 4 metals and ruler and a clamp a human beings of timber and some weights. We were apply our first piece of metal and accordingly set it 130mm over the contact of the table. We clamped the wood down by putting the piece of wood on apex of the metal near the edge of the table and accordingly put the clamp on the top of wood and at a lower place the table. And then we put a half kg weight on the top of it and if it didnt fall off we added to a greater accomplishment until it pious platitude take no more weights. because we measured how off the beaten track(predicate) down it deflected from the ground. 4.A Record Of The Observations And Results Of The Test ·         In this test we cut that the 7mm galvanise held the most weights therefore it is the strongest and the aluminium held the least and it was the weakest. The 67mm Copper was very weak aswell besides it still held out 2kg, 1kg more then the Aluminium.         1 kg         2kg         3 kg         4kg         4½ kg .7mm Galvanise         806mm         805mm         804mm         803mm         799mm . 67mm Copper         805mm         799mm         -         -         - .44mm Galvanise         799mm         -         -         -         - .57mm Aluminium         801mm         -         -         -         - ·         In this test we found out that 7mm Galvanise is once over again the strongest and the toughest when it comes to scratching, centre punch, biting and turn of eventsing, but when it comes to alter it burns a lot through it. The Weakest was the Aluminium it was ! easy to scratch, centre punch, cut, bend and also heating it would melt it. The Copper was the strongest in heating because all it did was change colour and the 44mm Galvanise would also change colour but would burn a hole though it as well.         Scratching         Centre punch         Cutting          digression          rut .7mm Galvanise          strong         3 bashs          actually lumbering          very(prenominal) Hard         Burns .67mm Copper          easy         2 Hits         Hard         Easy         Changes Colour .44mm Galvanise         Easy         1 Hit Easily         Easy         Easy         Burns, Changes Colour to park .57mm Aluminium         Easy         1 Hit Easily         Very Easy         Easy         Burns Through If you want to give out a full essay, order it on our website: OrderCustomPaper.com
