3. A large, 5-cm thick plate of pure aluminum initially at a uniform temperature of 200°C is suddenly exposed to a convection environment in which the fluid temperature is 50°C and the heat- transfer coefficient is 1200 W/ m K. Calculate the temperature of the plate at a depth of 1.5 cm from one of the surfaces after 3 min. How much heat is lost from the plate during this time? Ans: Tplate = plane

If the density of aluminum and gold are 2.70 E3 and 193 E3 kg/m^3 respectively. How much aluminium by volume would you need in order to have the same weight as a 4.20 kg piece of gold? Number Units If this piece of gold were a cube it would have sides measuring 6.01 cm, What would the sides of the aluminum be if it were also a cube? Number Units

If the density of aluminum and gold are 2.70 E3 and 19.3 E3 kg/m^3 respectively. How much aluminium by volume would you need in order to have the same weight as a 4.40 kg piece of gold? (I know the correct answer to this first part is 1.62x10-3 m3) If this piece of gold were a cube it would have sides measuring 6.11 cm, What would the sides of the aluminum be if it were also a cube? Please help...

The theoretical failure strength of high-purity and fully-dense aluminum oxide (Al2O3, alumina) can be up to 4 GPa ! In other words, a pristine alumina sample is expected to support this stress, even in tension, since no stress magnifying flaws would be present. Think about that for a second ... most metals yield (bend permanently) at stress levels on the order of 0.1 - 0.5 GPa ... and this is considered their upper limit for structural use. Ceramics like alumina...

Part 1 Before we can consider the effects it might have, we must consider the high tension power line itself. Such wires are frequently constructed by twisting aluminum or copper wires together into a large flexible bundle. Consider such a copper cable with a diameter of 4 cm. If this cable is 10 km long, what is its resistance? Remember: Resistance = Resistivity * Length / Area Resistivity of copper is 0.0000000168 Ω-m Cross sectional Area of...
