Talk:Simple machine

Immediate changes from WP

Besides removing templates and images, the first changes will make the examples more concrete, as, for example, changing the initial list of machines to a table including examples of tools, machines, etc., produced with them. Howard C. Berkowitz 16:35, 2 June 2009 (UTC)

suggestions for first table

Some of the items listed in this table appear to not belong where they're listed, and/or aren't good examples of the machine in question. I've made some suggested changes below - new items in bold, items to be removed in strikeout. I also think we can do away with the "animal power source" column entirely.

Simple machine	Basic application	Animal power source	Complex application
Lever	Pry bar, scissors Knife, Saw	Hand and arm linear force	Catapult, lock mechanism
Wheel and axle	wheelbarrow, cart Drill (tool)	Hand and arm rotational force	Automobile
Pulley	hoist Pile driver	Shoulder force (human) or harness	Elevator,Crane (engineering)
Wedge	Axe, Splitting wedge, knife, chisel	Pressure	Metal shear
Screw	Screw (fastener), drill (tool)	Rotational movement	Propeller, Archimedes' screw, screw conveyor
Inclined plane	Ramp	Pushing or pulling	STOVL aircraft roller coaster track

I can certainly live with the alternate examples, although I think there is merit in keeping the animal power source, which eventually might move toward something more biomechanical, with two- and four-legged distinctions. Howard C. Berkowitz 17:53, 16 June 2009 (UTC)
