What force is needed for the fans to work?
According to the Newton’s first law, the unbalanced force must act on a body to change its state of motion. So when the fan is switched off the external force of air friction acts on the fan and bting the fan to the rest. Thus, the frictional force of air acts as external force on the fan to stop it.

What is used in electric fans?
Electric fans made their first appearance in the 1880s. These early fans were made primarily of brass. Over the ensuing decades, fans were constructed out of a large number of materials, including steel, copper and aluminum. In the 21st century, most domestic fans are made out of plastic.
How does a fan work physics?
The fan works by pulling air in and then making it move faster. The air flow behind the fan is slow moving and wide (you can see the arrows behind the fan coming from above and below the fan blades) whereas the air flow in front of the fan is fast moving and narrow (which follows from the conservation of mass flow.
What are the forces acting on a ceiling fan?
Gravity, Normal reaction from the clamp, longitudinal drag due to the rotating blades, vertical lift due to the air pushed downwards, rotational friction,, Armature reaction Lastly the Electromegnetic force which is the main cause of its rotation.
What is the centripetal force in a fan?
There is a centripetal force pulling the blades towards the center of the fan. … There is air resistance pushing the fan in the direction opposite to its rotation. There is the driving force (from the motor) in the direction of the rotation, making sure the air resistance doesn’t slow it down.
How do you fix a fan that won’t spin?
Press the straw that came with your metal lubricant spray into the nozzle of the can. Shake the can several times and then put the end of the straw into the center of the fan blade unit and spray the lubricant several times. Rotate the fan by hand and do this again.
Why is there no air coming out of my fan?
The most common cause of low air flow through the vents in your home is blocked or dirty AC filters. … If you have pets that shed lots of hair, you may need to switch out your filters even more often. When you clean or change your AC filters, be sure to vacuum the metal grates closing the filters in at the same time.
Why is my fan not working?
This could be because the circuit breaker has tripped or is off. Check your panel to confirm this. If the circuit breaker works fine, it could be a problem with loose wiring and connections. Your ceiling fan could also stop working due to internal defects namely shot ball bearings or an overheated motor.
