do we have to memorize any equations

Equations...hmmmmm....F=MA and "You can't push with a string."

That's all you need...

sorry, couldn't help myself...:)
 
I remember a question that I'm still not completely sure about. A square metal plate is hanging by 4 wires (one on each corner). One breaks, and it's hanging by only 3 wires now. Does each wire now carry the same amount of weight, or do the 2 diagonally across from each other hold an equal amount that is more than the lone wolf in the other corner?
 
If the 'lone wolf' was doing any supporting, the plate would tip up on that corner. The two carry it alone.

Oh, and the plane takes off regardless of the treadmill setting.:D
