To prevent catastrophic damage, shipbuilders typically construct cruise ships using extra-strength steel and insert double hulls as an extra precaution. A double-hull design is a hull within a hull, like a tire with an inner tube. Unfortunately, accidents do happen. In order to prevent cruise ...
The name Ferrari brings many images to mind: a Formula One racer darting through the turns at Monte Carlo; vice cops chasing drug smugglers through the streets of Miami; ultra-rich drivers cruising winding roads in their six-figure trophy cars; the prancing stallion on a yellow background. Th...
Helicopters, fuel, equipment and manpower all figure into the expense of a SAR mission. This expense is passed along to U.S. taxpayers. In the case of U.S. Military SAR, the federal government picks up the tab, which of course comes from taxpayers as well. Only three states currently ...
This is one of the oldest designs for fuel cells; this type was the first the United States space program used to produce electricity and drinkable water on-board rockets and shuttles. NASA favored this method because the alkaline cell has high efficiency and a low operating temperature. However...
That buzzing noise can sound weird, especially when it’s louder with particular pieces of cookware for reasons that I have yet to figure out. On the other hand, I’ve decided that I like the beeps the touch controls make as I tap them; the experience feels a little like cooking on th...
This potential profile is designed to investigate the dissolution behavior in the anodic regime and its evolution towards cathodic potentials. Figure 1b displays the current densities measured for the material’s four different aging states. The positive currents in the anodic potential regime reveal ...
Figure 2 - Procedures for passivating stainless steel parts in nitric acid baths. Methods vary according to chromium content of the non-free-machining alloys treated, and according to the free-machinability characteristics of the alloys specifically identified. Nitric Acid Passivation of Stainless Steels...
Consider calculating the area of a piece of steel to know how large of a space it will cover. Steel comes in many varieties, but its area always depends on its physical dimensions, namely its length and width in the case of a rectangular sheet. In the case of a circular piece of steel...

You get a lead for an HVAC company that has all types of scrap air conditioners. The owner tells you that if you process it and sell it that you can split the money 50/50. You may think that you deserve more, but you have to figure that the material already has value to the HVAC...
