Thanks for all the replies, that seems to make sense and helps a lot.
This was what I look apart: https://www.amazon.com/dp/B000FABESC/?tag=pfamazon01-20
I opened up the case and spread out it's components, plugged the power back in and I was looking at the fan and it's airflow direction...
I did some research on how dehumidifiers work and from what've been able to find out, it takes in room-temperature air, cools it, thus condensation, then runs it back through heated coils so bring the air back to room temperature.
I got around to taking apart an actual dehumidifier it's...
I figured with how big the internet is, there would be an entire forum on magnets somewhere out there for me to ask my question but it turns out, if it does exist, I couldn't find it. So I figured you guys would be just as good, if not better :smile:
I'm building an object that has 2 halves...
My problem isn't very specific (I don't have any numbers for my constants, etc) and I said pretty much everything I do know. I think it's specific enough to know what I'm looking for though. I have a pretty good idea from everybody's replies, and enough work to present that even if I can't...
Well, by generator I meant something along the lines of those hand crank radios/flashlights, but on a little bit of a bigger scale. Based off another post, I know boiling water isn't very probable, but I'm just exploring other possibilities for hand generated energy. Originally I was...
Unfortunately, I can only follow about half of that. My problem isn't exactly restricted to these equations. I just need to figure out if I can generate enough heat by pushing a wheel. If all this is too complicated to figure out, would it be easier to solve if I used a generator as opposed...
It doesn't have to be very complex. I am ignoring frictional losses except for the brakes, and any other inefficiencies.
Do I need to change my equation and use \frac{1}{2}I_{cm}w^2+\frac{1}{2}mv_{cm}^2? If so, How do I get the rotational inertial and the angular speed? Assuming it's...
This isn't one of those textbook problems, but it's still homework, so I thought it'd be okay to post this here.
Homework Statement
I have a wheel with brake pads that generate heat through friction. Everything except the velocities are constant, and I'm trying to figure out equations to...
I actually don't have a lighter myself, and but my cell phone charger doesn't work when the car is off. My friend says his lighter works when the car is turned off though.
Maybe I'm just confusing myself but would it be KE=.5m((d1/t1)^2-(d2/t2)^2) assuming d1=d2 OR t1=t2? (1 being without breaks and 2 being with breaks)
This is assuming the energy difference is all caused by the brake pads of course.
Also. would this all apply if I'm heating a coil connected to...
Hi, I'm trying to use https://www.physicsforums.com/showthread.php?t=50668 for a design I'm working on, but the situation doesn't exactly match.
My idea was to use something like this (http://ecx.images-amazon.com/images/I/51KH24CPE0L._AA280_.jpg) with a flywheel and brake pads to generate...
