Do transformers have primary and secondary coils?
Do transformers have primary and secondary coils? A transformer has two coils – a primary coil and a secondary coil. An alternating current flows in the primary coil and this induces a voltage in the secondary coil. What are the 3 types of transformers? There are three primary types of voltage transformers (VT): electromagnetic, capacitor, […]
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, […]
What is the need for quick return mechanism?
What is the need for quick return mechanism? A quick-return mechanism is a subclass of a slider-crank linkage, with an offset crank. Quick return is a common feature of tools in which the action is performed in only one direction of the stroke, such as shapers and powered saws, because it allows less time to […]
What force causes a cylinder head to pull tight against the head gasket?
What force causes a cylinder head to pull tight against the head gasket? CLAMPING force What causes cylinder head failure? The most common reason for cylinder head failure is overheating caused by coolant loss, head gasket failure or restricted flow of coolant. In extreme cases a cracked or damaged cylinder head can result in terminal […]
