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

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.

Sodium hydroxide‚ also known as caustic soda‚[2][3] or lye‚ is an inorganic compound with the chemical formula NaOH (also written as NaHO). It is a white solid‚ and is a highly caustic metallic base and alkali salt. It is available in pellets‚ flakes‚ granules‚ and as a 50% saturated solution.[citation needed] Sodium hydroxide is soluble in water‚ ethanol and methanol. This alkali is deliquescent and readily absorbs moisture and carbon dioxide in air. Sodium hydroxide is used in many industries
