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. [[User:Howard C. Berkowitz|Howard C. Berkowitz]] 16:35, 2 June 2009 (UTC)

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.

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
