I saw a video of a windmill a few minutes ago and they are quite fast.
But then i thought “Is the tip of the rotorblade as fast as the the point furthest in the middle?”
Let me explain the best i can:
So if you move 10km/h, after 1h you are 10km farther than before. Thats logical.
But with regards to the rotor blade, the point furthest in the middle moves less far than the one all the way outside.
Does that mean that the points move at different speeds even though they’re part of the same body?
Where is my mistake in thinking?
In: Engineering
The outside of the blade moves faster than the center. If you find the circumference of the circle at the center and compare it to the circumference of the circle at the tip, the outer circumference is larger but they travel the distance in the same time. More distance/same time = faster speed
