A pulley is a simple machine consisting of a wheel with a grooved rim in which a pulled rope can run to change the direction of the pull.

What is the mechanical advantage of three pullies?
It depends on how you arrange the pullies and what you mean by 'three'. A pulley block can have 3 sheeves, it would have to be used in conjunction with another pulley block with either 2 or 3 sheeves and rigged to advantage or disadvantage. Or you could have 3 pulley blocks with a single sheeve in each and each one acts on the hauled part of the other, in tandem. Not enough information.
WHO HAS A Free energy machine?
One answer is "we all do" in that the sun is a free energy machine. If you are thinking of a box that will output electricity with no input (or some other useable energy medium) then the answer is "there is no such thing as a free lunch". Any energy conversion machine be it an internal combusion engine, a coal burning stove, or a sunflower costs energy to produce energy and it will always cost more energy in the total cycle than it will deliver. The exception to this is nuclear energy which delivers more energy than it takes to produce it. Actually nuclear energy is not really an exception as stated above,it takes more energy to mine,refine,and process the nuclear material into usable fuel rods and then dispose of the all the nuclear waste for 1 fuel rod than that fuel rod actually produces......especially when dumpsites must be maintained for 1000's of years to avoid contamination of the environment...... However there are as you call "magic boxes" that produce electricity with very little input....One such form of a free energy machine can be made with 2 heavy duty 300amp car alternators(generators), 2 heavy duty automotive power inverters for running AC eguipment & appliances,1 car battery,1 electric motor 5hp 110 volt 30amp,1 voltage regulator and a simple mounting system and some heavy duty wiring and a few switches... . The 2 alternators and electric motor are mounted on a rig in a "V" formation with the electric motor at the bottom center and 1 alternator in each upper corner,a belt is run around all 3 pullies and tightened..The car battery is then wired to power inverter #1 and has a dual cut-off/on switch installed before the inverter....then power inverter #1 is wired to the 5hp 110 volt electric motor.. Then alternator #1 is then wired to power inverter #1 via the dual cut-off/on switch previously installed above...(((a dual cut-off/on switch allows power to be shut off from one circuit while simultaniously turning on power to another circuit)))...a voltage regulator is also wired from alternator #1 to the car battery so that the alternator can charge the battery... Next alternator #2 is wired to power inverter#2 ((this circuit will provide all the necessary AC current))alternator #2 only powers the inverter.... Once all the wiring is completed the next thing to do is start the machine... this is done by turning on the main power switch installed on the positive battery terminal which sends current to power inverter #1 and the electric motor then begins to turn and spin the alternators producing electricity... Once the electric motor is running the battery is no longer needed so you turn the dual cut-off/on switch and switch from running the electric motor from the battery to running the electric motor from the electricity produced by Alternator #1 and power inverter #1.........Alternator #2 and power inverter #2 can be used to run AC power to eguipment and appliances... The amount of energy that is used by the battery to start the whole process is extremely low...... The battery is used only to start the electic motor spinning,after that the battery is not needed because the electric motor is running off of the energy that it is making alternator #1 produce......In theory this machine would keep producing energy at no cost until one of its components burned out... it is simply an electric generator that runs off of its own generated power.... It is applicable in small scale However if this application could be enlarged so that the huge generators of powerplants could be run on the same electricity they produce themselves then they would have essentially an endless supply at very low cost...
How many pullies can a pully maximum have?
24 pullies is the maximum pullies that a pully is able to hold
What are two types of pullies?

Make a sentence with the word lever?
I made this with simpe devices,like pullies and levers.
Why do fan belts twist?
Either one of your pullies are buggerd, or they are not lined up properly
How do you adjust pulley alignment on 1992 dodge caravan with a 3.3 liter engine?
If you have the correct pulley and two clean surfaces, the pullies should match fine and no adjustment is needed for alignment. It is possible you do not have clean surfaces or the pullies are not the correct ones.
What kind of robots did they have back in the past?
They had robots that ran on gears and pullies, power supply was steam (most likely)
Where is the Jeep Grand Cherokee serpentine?
The serpentine belt goes around all of your pullies in the front of your motor, behind the radiator.
Can you show a diagram for serpentine belt 1998 Jeep Cherokee?
NO - is this a GRAND Cherokee or XJ? What engine does it have? smoth side of belt, to smooth pullies, groved side to groved pullies. Only the right belt will fit. Hope you gave the parts store more info than us or chances are, you have the wrong belt.
Is there a diagram for fan belt routing on 1993 Ford F-250?
normally on top of the grill area in front of the belts and pullies.
How to repair cantilever patio umbrellas?
Take it down, lay it on your picnic table and try to 'follow' the string and pullies. Some may be worn, broken or rusted. If necessary, remove the strings and pullies and bring them to your local hardware store. Hopefully they might have the string and/or parts. If not, I located the following Umbrella repair site, which has links to parts and repair ideas.
