manufacturing the aircraft. Magnesium and Aluminium are two metals that are both renowned for being lightweight. Although they are not incredibility strong when they are in their pure state‚ they can be alloyed which provides the material with more strength. The material for the main skin of the aircraft needs to be as strong as possible whilst being as light as possible. Duralumin is an alloy that is used extensively for aircraft skin‚ it is a Aluminium - Copper based alloy‚ with 93.5% Aluminium

share for aluminium alloy usage in car bonnets is about 18% in Europe‚ 8% in America and 3% in Asia. These percentages decrease significantly with increasing part complexity [1‚ 2]. These applications require alloys having properties like a high strength to weight ratio‚ dent resistance‚ corrosion resistance and good formability [3]. Apart from material and manufacturing cost‚ the poorer formability of aluminium alloys compared to that of steels is one of the most important reasons for the relatively

The Shelby SB203 Charcoal Wheel is forged from a billet aluminum alloy for a lightweight and superior strength that no ordinary cast wheel can match. Featuring a 10 spoke design‚ the better corrosion resistance‚ increased strength and enhanced durability come on as a bonus. Warranty. Your wheels have a one year warranty against defects in the finish of your wheels and a lifetime worth of structural warranty. Drive

The die angle is 90. the flow curve for the work metal has a strength coefficient of 800 MPa. Determine (a) extrusion ratio‚ (b) true strain (homogeneous deformation)‚ (c) ram pressure‚ and (e) ram force. 2. A billet that is 75 mm long with diameter = 35 mm is direct extruded to a diameter of 20 mm. The extrusion die has a die angle =

For the testing of steel reinforcement they are determining the yield point and breakage point of the steel‚ while on the concrete cylinder testing they are only to determine the ultimate strength of concrete because concrete doesn’t have yield point. The last equipment they show us was the rainfall simulator which determines the

COURSE: The Chemical Environment TERM: 2 LEVEL: 7 ASSIGNMENT: 1 SESSION: 2012/13 TUTOR: Stuart Allan WORD COUNT: 1‚891 Carbon fibre is a strong‚ yet light‚ reinforced polymer. Carbon fibres are used in applications where high strength and light weight are required. Carbon fibres can also be easily moulded into the desired shape. They are also chemically inert‚ resistant to heat‚ and do not expand under changing temperatures. Machining of carbon fibre materials can generate

2013 Strength Within Strength is more than just a word. It is a word of high stature. Strength is the state of being strong. Strength is the power to resist force and attack. Strength is overall toughness. Strength is‚ in fact‚ a basic condition of life. We have to be strong in order to exist. Strength is definitely a very helpful thing to have because one uses strength in everyday life. A person must have strength to do certain things‚ whether physical or mental. We also need strength to enjoy
