An aerodynamic design reduces air resistance, which in turn increases fuel efficiency and top speeds. These designs often feature curved, rounded surfaces rather than flat ones because the air can pass over a sleek shape with less resistance.
When a base metal, such as aluminum or iron, is combined with additional elements, the resulting metal mixture is called an alloy. The advantage of an alloy metal is that its basic ingredients are greatly enhanced when blended together. For example, brass is an alloy of copper and zinc. When the two elements are separate, they are less durable and not as attractive as when they are combined to form brass.
Chromium is the 24th element on the periodic table, and it is the main ingredient in stainless steel. In fact, the reason that stainless steel is so resilient to rust, corrosion and tarnish is because of the high chromium content, at least 10.5%.
Condensation is basically a fancy word for the sweat that forms on a cold can of soda. However, it also refers to the actual physical transformation that takes place to generate that layer of dew. Here's how it works: the air that surrounds us is full of moisture, which is just water in gaseous form. When air cools, the relative humidity rises, saturating the air with more and more moisture. If cooled enough, the moisture actually shifts from its gaseous state back into a liquid, which then gathers on the surface of surrounding objects.
Drag is the word for air resistance that slows down your vehicle while driving. The effect is more pronounced at higher speeds. Drag is reduced by aerodynamic shaping such as curved edges that reduce the air caught by your vehicle.
