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 |
Hand and arm linear force | Catapult, lock mechanism |
Wheel and axle | wheelbarrow, cart |
Hand and arm rotational force | Automobile |
Pulley | hoist |
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 |
