Review Conceptual Example 5 before attempting this problem. To illustrate the effect of ice on the aluminum cooling plate, consider the drawing shown here and the data contained therein. Ignore any limitations due to significant figures. (a) Calculate the heat per second per square meter that is conducted through the ice-aluminum combination. (b) Calculate the heat per second per square meter that would be conducted through the aluminum if the ice were not present. Notice how much larger the answer is in (b) as compared to (a).

A corner fillet weld with cross sectional area of 75 mm is made using oxyacetylene welding. Material of the welded plates is low carbon steel (Um = 10.3 J/mm'. Travel speed at which the bead is formed = 5 mm/s. Assume that only 40% of the energy generated by the torch is used for melting the metal; the rest is dissipated. If heat of combustion for acetylene is= 54.8 MJ/m³ , determine the volume flow rate of acetylene required to perform this OAW operation.

Nickel-based alloys are used for gas turbine blades in aerospace engines. Briefly discuss the characteristics that make these alloys the choice for this application. Single-crystal technology is applied to nickel alloys that are used as gas turbine blades in aerospace engines. With the aid of sketches describe how a single-crystal casting can be manufactured and explain why a single-crystal casting is likely to have superior creep resistance than a directly-solidified one. Demonstrate the application of the Ten-percent Rule by calculating the approximate tensile strength and elastic modulus in the 0° direction of a carbon-fibre reinforced polymer composite if the strength and elastic moduluş in the 0° single ply are 3620 MPa and 143 GPa respectively. The lay-up sequence of the composite is [02/+45/-45/902]s.
