Question

QUESTION 1 Porsche AG is a leading manufacturer of performance automobiles based near stuttgart, Germany. The company wants to acquire a bigger market share (i.e, sell more) of the compact sports car segment with the Boxster. They are interested in designing a new and less expensive body to meet the increasing pressure for less expensive automobiles. Answer the following 3 questions. a (5 points) Select a body material to meet the new strategy b (15 points) Describe and justify the physical properties lat least 3] of the material you selected c.

Answer 1

a) Aluminum can be used. This is because aluminum is less costly and the weight of the aluminum body is less so the performance of the cars will enhance.

b) Physical Properties of Aluminum:

Light Weight
Aluminum could be a flared metal with a particular weight of two.7 g/cm3, a couple of third that of steel. for instance, the employment of atomic number 13 in vehicles reduces dead-weight and energy consumption whereas increasing load capability. Its strength may be tailored to the appliance needed by modifying the composition of its alloys.

Density of Aluminum
Aluminum incorporates a density around one third that of steel or copper creating it one in all the lightest commercially accessible metals. The resultant high strength to weight magnitude relation makes it a vital structural material permitting accrued payloads or fuel savings for transport industries particularly.

c) Mechanical Properties:

Ductility
Aluminum is ductile and includes a low temperature and density. during a liquefied condition, it may be processed during a variety of how. Its malleability permits product of atomic number 13 to be essentially shaped near the tip of the product’s style.

Strength of Aluminum
Pure Al doesn’t have high lastingness. However, the addition of alloying components like metal, silicon, copper, and metal will increase the strength properties of Al and turn out an alloy with properties tailored to explicit applications.

Aluminum is well matched to cold environments. it's the advantage over steel in this its’ lastingness will increase with decreasing temperature whereas retentive its toughness. Steel, on the opposite hand, becomes brittle at low temperatures.

Corrosion Resistance of Aluminum
When exposed to air, a layer of corundum forms virtually outright on the surface of Al. This layer has wonderful resistance to corrosion. it's fairly immune to most acids however less resistant to alkalis.

Recyclability
Aluminum is one hundred pc reusable with no downgrading of its qualities. The re-melting of atomic number 13 needs very little energy: solely concerning five p.c of the energy needed to supply the first metal at first is required within the utilization method.
