So as I am sure everyone was aware of, this weekend was the weekend before finals. What does that mean? Well, for me that usually means trying to get as much information into my head again (and this time retain it for a while longer) before getting swept up with all the other things that happens during school. Unfortunately, I can only go on to study for only so many hours at a time. Eventually I have to give my head a rest in order to start shoving more things back into my head. And what's the best way to mindlessly do something? By looking at a fan! Unfortunately for my brain, I saw that blades of the fan had torque which is the force times the radius, in this case the length of the blades. The fan while spinning also had moment of inertia which is the mass x radius squared. Also, when I turned on the fan, it had angular acceleration which is equal to the net torque over the moment of inertia. So much for a mindless activity.
