POSSIBLY A MACHINE:
Bicycle
Garden Weasel
Swiss Army Knife
Cheese grater
Lava Lamp
Suction Cups
PROBABLY NOT A MACHINE:
Pop Tart
Mud Turtle
Chap Stik
Play Dough
but wouldn’t the little screw count inside the chap stik count? it’s a lever!
Fippo-
Uh-Oh! The truck have started to move!
You may have a point Fippo. I was focusing on the waxy stuff, but I think your right.
Why should there be a point? Did they change the name of the forum? What about the premise that all mechanical machines can be reduced to variations on the lever and the inclined plane?
The best lack all conviction
The worst are full of passionate intensity.

I give. What makes a cheese grater or a suction cup a machine? Neither has moving parts.
And if the mud turtle is an actual amphibious creature, as opposed to some reference I don’t get, I think it IS a machine. If it’s parts didn’t work together with levers (muscle and bone), how could it locomote?
Spiritus, I think you left out one of the simple machines, the hydraulic press.

I thought a screw was a inclined plane mapped onto a cylinder.
It is.

The cheese grater is made of several parts (if you consider the cheese a part) that use energy (your arm I assume).
The turtle is debatable.
Hey, I’m looking for a fight!

Oh, and the little flexable wings of the suction cups might be considered moving parts.
Oh, sure, now that you’ve put it that way, the “cheese grater + cheese + arm system” does qualify as a machine. But really only the arm should count on its own. I mean, what kind of work does cheese do? Or the grater by itself?
And if the arm is a machine, then the turtle’s a machine, too.
As for the suction cup, I guess if you wanted to call it an inclined plane, you could, but the logic is a little contrived.
Lots of questions - no good answers.
Here’s a point for this pointless topic:
In Virginia, like other states, animals, pedestrians, and bicycles aren’t allowed on the interstate highways. But instead of being simple about it, they have a very wordy sign. One of the things not allowed on the highway is “self-propelled machinery”. What that defines is every car, truck, or bus! It’s not like they’re getting their power from a third rail or anything.
We need signs like that where I live. Then maybe the deer’d know to stay off the roads.
Seriously though, I like my machines well oiled.
