Principles of Engineering Design Coursework Report: Design of a Bicycle Frame Introduction Bicycles‚ whether they be mountain bikes or just ordinary street cycles‚ play an important role in society‚ especially in sport and in general means of transportation. The history of bicycles and their contribution to an economical means of transportation goes as far back as the 19th century. Bicycles have progressed and evolved ever since and ever improving with the introduction of spoked wheels‚ a chain

Introduction: Iceland is located between Norway‚ Scotland and Greenland in the North Atlantic Ocean. It is also the 2nd largest island of Europe. Iceland’s economy is based on the Scandinavian type capitalistic system‚ also known as the Nordic Tiger because of its rapid growth. With a population of only 312‚872 people‚ it is ranked as a country with highest HDI and one of the highest GDP per capita PPP. Iceland is a modern welfare state which provides health‚ education and security to all its

the lift. But then‚ the material used must not be too fragile as it has to withstand high pressure and impact from foreign objects such as birds. The main material used is a type of stainless steel metal‚ which is aluminium. But then‚ in order to withstand a high pressure the aluminium layer must be very thick and thus the weight is increased. So‚ the engineers got their idea from the short bow invented by Genghis Khan which wrapped the inner part with a layer of elastic fiber. Then‚ they tried to

Chemistry : 1. Aluminium hydroxide on thermal decomposition gives aluminium oxide and water 2. Iron (iii) oxide reacts with carbon forming iron and carbonmonoxide 3. Hydrogen peroxide reacts with lead sulphide forming lead sulphate and water 4. Lithium reacts with nitrogen forming lithium nitride 5. Nickel sulphate reacts with sodium phosphate to form nickel phosphate and sodium sulphate 6. Silver oxide reacts with hydrogen peroxide to form silver ‚ water and oxygen 7

present the data in a suitable format for evaluation and analysis. Introduction This experiment was conducted to determine the conductivity and expansion of the metals at different temperature. The four metals which have been used for this test are aluminium copper‚ brass‚ and iron. The four metals are placed on the circular wooden frame which is fixed opposite each other with the strips meeting at the centre. Once heat is applied on the centre of the circular wooden frame‚ the lengths of the metals

Complex shape can be extruded from the more readily extrudable metals such as aluminium. * The products obtained are also called extrusion.
