Since the invention of rotating machinery, gears are known for their force multiplying properties. But did you know…  
 
Greek mathematician Archimedes (287 B.C.—212 B.C.) designed a number of machines that utilized gears?
Many early gears in industrial applications were made of wood with cylindrical pegs for cogs and lubricated with animal fat?
You can find a more cost-effective solution for your gear requirements by turning to powder metal (PM)?
