Deep into trivial thought....

Did you ever wonder why the heater fan in your car operates from low- medium-high, while a typical box window fan operates from High-medium- low? I was just thinking about that. hmm.... Oh yeah, I never figured out how 8 "bits" could equal $1.00 either... We will all try to put your mind at ease: With the fans, the car is a DC motor and the window is AC. Starting torque is different. As for the bits ..... isn't 2 "bits" a quarter? But you can take a window fan and set it on "low" , plug it in, and it starts up jjust fine, though... True, but it's not particularly good for the motor. Ideally, it should start up on "high" to give max torque using all the windings of the motor. Then, it can be turned down. Not a big deal though ... most fans can handle it. I forget the mechanical stuff, but it takes something like 3 times the amount of power to get something in motion than it does to maintain that motion. Newton's Laws of Motion: force is redundant and subordinate to the conservation of momentum. Ipso facto, quid pro quo, illegitimi non carborundum. Carpe Diem. :) Burma Shave.... |
