Homework Statement


We have to build a device that can move across a wire. There are two parallel wires, both very thin, 14.5 cm apart, seven feet above the ground, and we have to move the device the length of the classroom on the wire as fast as possible. We are allowed one motor, one 3 Volt or less battery, and we can use one wire or both wires. Also, no legos or building toys allowed.


Homework Equations





The Attempt at a Solution


I was thinking of having wheels, connected by a metal rod, lie across the two wires, one wheel resting on each wire. The motor would touch the outside of one of the wheels, so both of the wheels would move. Also, it would be good to use a 1.5 Volt battery because it gives a lot of power but it is not too heavy? . . .
Please post your suggestions!!!!
Thanks!

I'd just hang the battery and motor below one wire, and transfer the rotational motion to a single rubber wheel above the wire (that the motor and battery are hanging from). I don't see any advantage to using two wires.
