Why does a rotating fan blade look like its stationary at times?

your eye can only see about 24 frames per second. so when a rotating fan rotates with 24 rounds per resond or 48 rounds per second and so on, your eye will take a "picture" of the fan at excatley the same spot. Your brain then put these immages after each other an you wil see a rotating fan witchs looks like it isn't rotating. I hope you understand my English;P and I hope this answer helps.

Why does if helicopter's blade move really fast it looks like its rotating backwards?
just because haahahaha
What is a saw and what is it used for?
A saw is used to cut things. It can be hand powered or electric. It can be hand held or a stationary machine tool. It may have a straight steel blade or a round steel blade, it may have a loop blade like a band saw.
Why does if helicopter's blade rotate really fast it looks like its rotating the other way?
Because you have some kind of seeing disorder.
What is the difference between MRI Flair and MRI Flair Blade?
The plane of acquisition in BLADE is rotating, vs. a standard FLAIR has a single direction plane of acquisition (e.g. axial or sag). For BLADE, picture a plane rotating on a point like a see-saw, but 360 degrees. BLADE has been demonstrated to correct better for motion and Gibbs artifacts. See Wintersperger et al, 2006 in Investigative Radiology.
Tile saw and cut off saw?
Tile saw, the blade runs in water and is like a small table saw. Cut off saw can use water but usually is dry and is a chop saw. The blade come down into the tile or brick which is in the stationary base.
What is a nother word for stay in one place?
it is 'stationary', not stationary' as in materials, but 'stationary' as being still or something like that.
What is the definition and acronym for bit?
acrnym: binary digit or built in test definition:there are three a. a removable drilling or boring tool for use in a brace, drill press, or the like. b. a removable boring head used on certain kinds of drills, as a rock drill. c. a device for drilling oil wells or the like, consisting of a horizontally rotating blade or an assembly of rotating
How does the victa lawn mower work?
The Victa brand is a basic rotating blade lawnmower. The blade rotates at the same speed as the crankshaft of the engine The neat thing is that these mowers have a fan disk and a feature so that if the blade strikes something solid like a large rock it shouldn't destroy the engine. It will still cut off your toes though. And I bet it does a good job mulching.
Where can I find personalized stationary?
Well you can get personalised stationary online at special sites or you could get the items required to personalize your own stationary at a website like ebay.com.
Why not rotating magnetic field produced in three phase transformer?
When the three phase stator windings are fed by a three phase supply, a magnetic flux of constant magnitude, but rotating at synchronous speed is produced. The flux passes through the air-gap, and cuts the rotor conductors which yet are stationary. Due to the relative speed between the rotating flux and the stationary conductors, an emf is induced. ( Faraday's laws of electromagnetic induction ). Since the rotor bars or conductors form a closed circuit, rotor current is produced whose direction as by the Lenz's law, is such as to oppose the very cause producing it. In this case, the cause which produces the rotor current is the relative velocity between the rotating flux of the stator and the stationary rotor conductors. Hence, to reduce the relative speed, the rotor starts running in the same direction as that of the flux and tries to catch up with the rotating flux.
How do you use the word vane in a sentence?
The weather vane indicates the direction of the wind.A. 'The vane in that turbine needs an overhaul'.Vane is a broad blade attached to rotating axis or wheel.
