1. Structural steels have traditionally been used in shipbuilding; however, with

increasing fuel costs, it is desirable to find alternative lower weight materials.

Some of the key properties required for shipbuilding materials are high yield

strength, high corrosion resistance, and low cost. Discuss the benefits and

disadvantages of aluminum alloys as a replacement for structural steels in ships.

Solutions

Expert Solution

The alluminum is the most abundant metal in the earth but we can't find it pure but in a mix with differents materials. The alluminum alloys are very use in the industry because mix with different materials can have a number of properties that can varie according to the substance that is used.

Benefits:

The alloy its considerable lighter than the pure material, because the alluminum its a very ligthmetal.

It has a high resistance to corrosion because the alluminum can form Al2O3 that once formed its very hard to continue with the corrosion

Its a very unexpensive material

Disadvantages

The alloys has to be an equilibrium between the good and the bad, if an alloy has a very big amount of alluminum it will not have a very big mecanic resistence so it won't work as a replacement for structural steel.

On the other hand if it doesn't has an enough amount of alluminum won't have an enough covering of the coat that protects against the corrosion.

1) Three compounds that have been used as fuel in cars and racing cars are ethanol, nitromethane (CH3NO2, ΔH°f = -105.65 kJ/mole), and gasoline. Using octane (ΔH°f = - 208.24 kJ/mole) as representative of gasoline, calculate the following quantities for each of the three compounds: ΔH° of combustion per mole of the fuel, moles of gas produced per mole of fuel at 25°C and 1 atm pressure, heat (q) produced per gram of fuel, liters of gas produced per gram...

XYZ Corporation has traditionally been a ski producer. However, due to several years with little snow, they are exploring the opportunity to start producing umbrellas as they can use some of the waste material from the ski production to make umbrellas. To start producing umbrellas, they have to buy machinery for $1 million. The machine will have a life of 10 years and will be depreciated linearly over 10 years. At the end of the 10th year, they expect to...
