one blade of fan is parallel to the floor. what degree of rotation of the fan puts the blade at the top of the fan
does anyone know this?one blade of a fan is parallel to the floor. What degree of rotation of the fan puts the blade at the top of the fan?
It depends on which side the blade is on when it is parallel. If it just travels one-quarter of the way = 360º/4.
If it has to travel 3/4 of the way = (3/4) 360º
To determine the degree of rotation that puts the blade at the top of the fan, we first need to consider the number of blades on the fan.
Most fans typically have either 3 or 4 blades, but for the purpose of this explanation, let's assume we have a 3-blade fan.
In a 3-blade fan, the blades are evenly spaced out at 120 degrees each. When one blade is parallel to the floor, the adjacent blades will be at a 120-degree angle to it.
To rotate the fan and bring the blade to the top, we need to rotate it by an angle equal to one-third of the full rotation, which is 360 degrees.
So, to calculate the degree of rotation required to put the blade at the top of the fan:
Degree of rotation = 360 degrees / Number of blades
For a 3-blade fan, the degree of rotation would be:
Degree of rotation = 360 degrees / 3 = 120 degrees
Therefore, a rotation of 120 degrees would bring the blade from the parallel position to the top position in a 3-blade fan.
