A tornado's spin originates in wind shear, which is a difference in wind speed or direction at different altitudes. If this wind shear is strong enough air may start to roll in a phenomenon called horizontal vorticity. The updraft of a thunderstorm can then turn this vorticity vertical and take on the rotation to become a mesocyclone. Under the right conditions the mesocyclone can tighten and intensify to produce a smaller, stronger vortex: the tornado itself.
usually when you want to push air you turn the blade clockwise. When you want to pull air
you guessed it...counterclockwise.
magnets make a fan spin
reeeeee
Bearing.
AnswerLeft, counter-clockwise. Lefty loosey, righty tighty. --------------------------------------------------------------------------------It depends on which way the crank rotates. If it rotates clockwise the nut will be threaded on counterclockwise to prevent it from loosening. If the crank rotates counterclockwise then the nut will be threaded on clockwise.
it burns
Axle
the spindle of a CNC machine rotates the cutting tool.
A wheel or the blades of a fan.
Ceiling Fan rotates about a vertical axis. Top rotates about its own axis
There are three speed settings for this fan and it rotates 90 degress.
The blades of the fan have a small angle tilt, so it can push down air.
50
Air moves in opposite direction and if it's on a car-it will overheat
Lefty loosey to remove the fan clutch but the fan assembly rotates CCW when the engine is running.

Much dust is greasy and this aids its accumulation by impact. You'll find that the dust from a fan blade does not easily fall apart.
A fan motor has two parts namely rotor and stator. In a table fan blades are attached to rotor and its movement appears to be clockwise. In a ceiling fan, blades are attached to stator so blades appears to be moving anti clockwise.
The human eye just can't focus on an object moving that fast.
the fan usually absorb about 1 hp for evry 15 to 20hp of output .it rotates by power produced in engine via belt
