Which crystal structures are close packed?
Which crystal structures are close packed? It turns out that face-centered cubic and hexagonal close-packed crystal structures pack atoms equally tightly. Some metals with hexagonal close-packed crystal structures include cobalt, cadmium, zinc, and the α phase of titanium. What are closed packed structures? The term “closest packed structures” refers to the most tightly packed or […]
Why is ice on wings bad?
Why is ice on wings bad? Ice in flight is bad news. It destroys the smooth flow of air, increasing drag while decreasing the ability of the airfoil to create lift. Ice accumulates on every exposed frontal surface of the airplane—not just on the wings, propeller, and windshield, but also on the antennas, vents, intakes, […]
