Why does a ceiling fan have only 3 blades?
Fans can have any number blades--even one! (but then you need a counterweight for balance). There are airplanes that have one blade for a propeller. There are many variables that figure into how many blades a fan has. Air velocity, noise, shape of the blade, length of the blade, material cost, vibration, etc. For airplanes sometimes they change 2-bladed propellers for three or four or more to get different flying characteristics.
How long will it take for a wind turbine to offset its carbon footprint created during its construction?
It depends on the size, but usually three or four months.
What is the Difference between a turbine blade and a compressor blade?
A turbine is a machine that has a rotor of some sort that spins as a reaction to the flow of a fluid of some kind. A generator can be one of may things, but we often associate that term to a piece of equipment that converts mechanical energy into electromagnetic energy, or electricity. That said, the turbine could be connected to the generator to produce electricity from mechanical energy. The turbine is all about mechanical energy, and the generator converts mechanical energy into electric energy.
What turns the propeller of an airplane?
A propeller is a very complex airfoil, and its pitch (the "slant" of the blade) is not the same throughout its length. Think about it. The tips are moving very fast (many feet per minute) through the air compared to the parts of the blade near the center or hub. We want to force developed by the blade to be "somewhat the same" along its length, with a bit more near the hub where it's stronger. Use the link below to see how a three-bladed, variable pitch design is manufactured. Be sure to let the first few seconds of "other stuff" go by before the start of the segment on the manufacture of the propeller, okay? And while you're at that site, look at the other related video clips listed on the right. It's really interesting stuff!
What are the three different parts of the backsaw?
Blade, back and handle. The blade is the thinner steel that have teeth filed along the lower edge. The back is the rigid steel or brass (often brass plated steel) spin that the blade is pressed into and is there to keep the blade straight and true during the cut. The handle is usually fixed to one end of the blade by anywhere from two to six flush nuts and screws, one often specially stamped by the saw's manufacturer to display their logo and define the date of production.
When was Three-Bladed Doom created?
Three-Bladed Doom was created in 1976.
What weapon does hidan have?
The three-bladed syth.
Why are the wind turbines today three bladed?
The number of blades involves design considerations of:-aerodynamic efficiencycomponent costssystem reliabilityand finally aestheticsOver the last 50 years wind turbines have almost universally used either two or three blades because while aerodynamic efficiency increases with number of blades, it does so with diminishing returns.Thus increasing the number of blades from one to two yields a six percent increase in aerodynamic efficiency, and increasing the blade count from two to three yields only an additional three percent in efficiency.This means that increasing above three yields minimal only improvements and put up the component costs of the turbine (the fewer the number of blades, the lower the material and manufacturing costs will be).In addition, the fewer the number of blades, the higher the rotational speed can be because blade stiffness requirements to avoid the blades bending to hit the tower limit how thin the blades can be. Higher rotational speeds reduce peak torques in the drive train, resulting in lower gearbox and generator costs.Also three blades give system reliability because cyclic loads, when combined together at the drive train shaft, are symmetrically balanced for three blades, yielding smoother operation during turbine yaw.Finally, aesthetics can be considered a factor, most people find that the three-bladed rotor is more pleasing to look at than a one- or two-bladed rotor.
Is a four bladed helicopter better than a two bladed helicopter?
The concept of "better" does not work into it. Each rotor is designed for a particular purpose, for that particular helicopter. Sometimes the best solution is a two bladed prop. sometimes three, sometimes four, all depending on a wide variety of parameters. It's is analogous to knives. A table knife is designed for certain purposes. A hunting knife is designed for certain purposes. Both work perfectly for the purposes they were designed for, but they are hardly interchangeable, and one is not "better" than the other.
What are the designations of a three-prong plug?
On a three prong plug there will be a neutral blade, a "hot" blade and a ground blade. The neutral blade is wider that the "hot" blade. In North America the ground blade is "U" shaped.
Why the gas turbine needs 3 bucket stages only in 110MW TURBINE?
because all gas turbine has three stage buckets

Which blade is the longest in a 3 pin plug?
The ground blade is the longest in a three blade plug.
What is a three body blade?
It is a blade used by the Japanese that can cut through three bodies with one swing
What are the three main fuses?
not sure what electrical system we are talking about. In-line, regular sized two bladed, mini two bladed type, and a 50AMP sheet of metal type I have seen on a Rabbit diesel
Why are wind turbines three bladed when more blades should catch more wind?
the reason there is only three blades is because four blades would add weight and wind resistance, in some countries they use two or four bladed turbines though. \
