AI Thread Summary
To create a compound machine with three steps using simple machines, consider using gears, pulleys, and levers, as they offer numerous combinations. For making gears from household items, drilling holes into a wooden disk and inserting dowels can serve as teeth, mimicking DaVinci's method. Alternatively, carving teeth directly into the disk is another option, though it requires more effort. The discussion emphasizes the need for creativity and resourcefulness in utilizing simple machines for project completion. Engaging with these ideas can lead to effective solutions for building a compound machine.

Welcome to PF, Please.
By 3 steps, do you mean that you have to use 3 different types of machine to achieve your final result? If so, gears, pulleys, and levers are probably the easiest to work with. There are thousands of different combinations of those.
 
i need some help, i have a project using the six simple machines due on 10/21/09, if anyone can tell me how to make a gear(s) out of household objects before 10/21/09 will be greatly appreciated, thanks :]
 
Welcome to PF, Mkinator.
You won't get much in the way of accuracy, but the easiest way to make a gear is probably to drill holes into the circumference of a wooden disk and insert dowels to act as teeth. That's how DaVinci made his. You could also carve or saw teeth out the the disk itself, but it would be more work.
There are more ways, but those are probably your simplest options.
 

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
