i have to make a chain reaction machine with all 6 types of simple machines. can someone please tell me how i can use a screw? thanks
Perhaps you can use it as a timing mechanism (to pause the machine perhaps).
Have the screw wind down before starting the nest phase of the chain reaction.
The screw doesn't have to fasten anything necessarily, does it?
Hope this helps!
what about like a domino sort of thing...
