A ventilation fan has blades 0.25 m long rotating at 20 rpm What is the centripetal acceleration of a point on the outer tip of a blade?

a = v^2/r
.
r = 0.25 metres
v = ((0.25 * 2 * pi * 20) / 60) = 0.5236 metres / sec
so:
a = (0.5236^2) / 0.25
.
a = 1.097 (m/s)/s

An electric ceiling fan is rotating about a fixed axis with an initial angular velocity of 0.300 The angular acceleration is 0.898 Its blades form a circle of diameter 0.760?
What do you want to know about it?
How are the rotor blades of a helicopter tilted when rotating?
They are on special hinges attached to what is called a 'swash plate'
How ceiling fan convert electrical energy into mechanical energy?
The motor does it, by producing a rotating magnetic field, which twists the fan blades.
How do you know that the forces on a windmill are unbalanced?
When the forces on a windmill are unbalanced, the blades may slow down or speed up, or they may change direction. When the blades are rotating at a constant velocity (speed and direction), then the forces are balanced.
How wind is captured in a wind turbines?
The wind is captured by the blades of the wind turbine, which are aerofoil shaped. The force drives the blades which are precisely angled by a computer system to make the most efficient use of the available wind. The rotating motion of the blades attached to the hub, drives a gearbox which increases the rotating speed from the hub. The output of the gearbox spins a 3 phase generator at high speed that is computer matched to the existing grid frequency, supplying it with power.

What is a wind turbines width and height?
Its width is the diameter of the circle formed by the rotating blades, it has two heights, the height to the top of the tower and the height to the top of the circle formed by the rotating blades.
What is it that hits the fan in the idiom?
Excrement - it is "when the excrement hits the rotating propeller blades."
How does a helocopter fly?
The rotating blades form an air screw and screws itself into or out of the air.
Do wind turbines generate electricity all the time?
Only while the blades are rotating.
Why does your craftsman riding lawn mower die when you engage the mowing blades?
check to be sure the blades have free movement. usually if you have this problem it is caused from something stopping the blades from rotating therefore it stops the engine
Why do large fan blades take LONGER time to stop rotating than shorter blades?
Because of larger momentum. Larger bodies have larger momentum.
What are Self propelled aircraft with unpowered rotating horizontal blades?
Auto-gyros. (I edited the Question to as "What are" these.)
How are the rotor blades of a helicopter tilted when rotating?
They are on special hinges attached to what is called a 'swash plate'
Why isn't your riding lawn mower cutting grass?
Assuming the blades are rotating but not cutting grass, the blades may be very dull or they were replaced upside down when removed for sharpening.
