Every Simple Machine in One Rube Goldberg Machine?

Question

I have been assigned a Tech project and I have to incorporate every simple machine into one long sequence of machines that will be started by touching one end. Once touched it must run by itself. It must last longer than 5 seconds and fit on a 1 foot by 1 foot wood board. All machines must take advantage of their mechanical advantage (i.e. no rolling down incline planes or screws). I am allowed to use any materials I can find. Any ideas on how I could make this work? Especially, how can you make use of a screw?

Actually I do need an incline plane and a screw, but I have to use its mechanical advantage. For example you must go up an incline plane or screw a screw in or out of something, not just slide down a inclined plane or screw shaped slide.

Answer 1

I think you can consider something like a rubber-band driven fan, and the wind pushing a sail-car, a tower with a rubber-band-driven axis and a wire welding on it and lifting a mass.(the tower has the advantage to need relatively a little space....it uses vertically...so you save space on your foot^2)
Can you also use electricity? because this can be an interesting field....and magnetic fields?...and fluids flowing in or out ?
I think that your biggest problem is space and time, because if you use very fast simple machines you will need too much space to last longer than 5 seconds.....

Answer 2

That's a tough one! So you need to use all the following?
-The wheel and axle (O)
-The lever (T)
-The pulley (U)
-The wedge (V [single wedge]; X [double wedge])
-(but with no screws or planes? Then later you asked how to use/incorporate a screw so I don't know...) - This should help:

Use or make a Mouse trap!... have the trap-snap be activated with a wedge and pull a string that goes over a pully on an axle suspended by a coat hanger or something bent to your desire. You can even wrap the string around the pully (like use a thread spool or something) (IF the pully is attached to a nut on a threaded rod you have your screw)
Because the spool will have a lot of force to it and spin few rotations... attache a larger wheel to it..(a toy wheel or something 3-6inch in diameter perhaps.) Wrap thread around that wheel and tie a weight to it. (or you could make a paper airplane and use the thread to catapult (incline plane) a paper airplane into the air!...) I could write a book on the options! Think OUTSIDE the BOX! And Good Luck!

Answer 3

A rube goldberg machine is not the problem, ideas are the problem

Answer 4

you can have a screw-like slide
