Discussion for Screw task.

does the screw itself have to move back and forth or can it be like a wing nut on a threaded rod moving up and down?

Rule 4.d says: "Turn a screw so that its tip stays in contact with an object..."

That seems to indicate that the screw itself has to move and the screw's linear movement pushes the object.

now for a screw does it mean the simple machine?

Yes.

What would be an example of this type of simple machine? Also could this double up as the wedge one by having a screw push the wedge between two objects?

Do we have to use a screw? Can we use a bolt?

Provided it has threading like a screw, yep.

The bolt is a giant screw (it has a pointy tip and doesn't go into a nut). Is that ok?

Yep, so long as that pointy tip is staying in contact with an object, and you move that object by spinning your bolt.
