I love Shamu and people need to take a ride in their shoes or in this case Fins! It`s not his/hers fault because sometimes animals just have bad days like humans.

But even in the middle of the night.... its still white so the idea of it reflecting only daylight doesn't, well, wash?

can someone please explain the squeeze theorem to me. this theorem is sometimes known as the pinch theorem and sandwich theorem. please try to explain it in simplest terms.

Thanks.

I realize there's no specific formula for this, but any rough idea how the rpm would vary if say I had a 12V dc motor currently at 1,000 RPM unloaded. If I was to then add 200g on an 8cm long rod centred perpendicular to the motor, what effect would this have on the RPM?

Oh, and are the torque-rpm gradient values for the motor irrelevant in this case because the load is vertical (i.e. parallel to the axis of rotation and not perpendicular to the 'radius')?

Any advice much appreciated!

Imagine a small device that resembles a ferris wheel. There are magnets spaced equally around the rim. There is another strong magnet at the bottom such that when the wheel turns each magnet around the rim passes close to it and is pulled by it causing the wheel to speed up.

Normally the wheel would slow down again as the rim magnet passes the stationary one and is attracted in the opposite direction. I get that. But imagine each rim magnet is enclosed in a small superconducting box which blocks magnetic fields. One side of the box has hinges so that it can open as it approaches the stationary magnet and thus the magnet within will be drawn toward the stationary magnet and speed the wheel up. As it passes the stationary magnet the box closes preventing the attraction that would normally slow the wheel again.

A bit of the wheel's spin energy is used to open and close the box but if the wheel is large enough and the boxes small and light enough there should extra energy left over.
