- An Aluminum wire has a radius of (5.0) ∗ 10^−4?, this type of wire is being considered for use in a device that draws (3.5) ∗ 10^2 ? of power when it is supplied from a 120-V wall outlet. The person in charge of the project states that if more than 800? of wire is required then the project will not be viable. Will the length of wire meet this requirement? What is the length of wire?

CODE 102_8 Welding Many welding processes require the application of heat and/or pressure to produce a suitable bond between the two parts being joined. There are a number of conventional and commercially practiced welding processes, which possess limitations in relation to material type and thickness, and in addition, the cost analysis may not allow for a process to be used on a specific application. The selection of suitable welding consumable (electrode or wire) is also an important factor in producing...
