The simple machines in a faucet are: # A wheel and axle. # A lever (the handle). # Gears (probably inside the faucet). I'm pretty sure these simple machines are in a faucet, but I'm not sure if there are others. I've never looked into a faucet before...so, no experience. Thanks for reading my answer!
The cutting edge is a wedge, and the length between the handle, the hinge and the blade is a lever. Two simple Machines together makes a compound machine.
vending machines should be allowed in school for kids that don't have snacks or drinks. I think they should be allowed

The answer to this question is highly dependant on your drum machine. Usually the answer is yes, some drum machines will have a usb port allowing them connect directly to the computer. If it does not have a usb port you're not yet out of luck. Most drum machines should have a MIDI port, you can get a MIDI to usb connector that should handle your needs. Software and drivers I'll leave up to you.
