how does a pneumatic screwdriver works?

All Pneumatic tools are powered by an air compressor, much like the tools powered by other sources like electricity, gas, etc.

When a bolt is tightened, it stretches.\nThink of the thread as just two, long inclined planes in contact with each other. The tension in the bolt results in the two planes being pressed together, the harder you press, the greater the friction. As you undo the bolt, the tension is reduced, the pressure is reduced and so the friction is reduced.

pneumatic operated butterfly valves with 3-15 psi control using a 4-20ma I to P converter based on a voice coil type machanics, don't try one of the 4-20 ma electronic I to P converters, Radio frequency, Variable frequency drives, Changes in grounding, make the electronic I to P converters less accurate and reliable. Add a 4-20 loop to the position control and your world will be perfect.

On-off valves can have mechanical, pneumatic, hydraulic or electromagnetic actuation. See ref.

Elements of a Pneumatic installation are often available\nand easy to find, I know what you want to build, then list\nthe elements and buy it. If you just want to see how it works, you can buy a kit (search internet to find it).\nMost expensive member can be the compressor.

It is simple, open a old mouse and see, there are two wheels,  one is for horizontal movements and the another one is for vertical movements. when you move the mouse up&dowm the vertical mouse whell will rotate, while rotateing there is a LED and sensor will contact eachother, then the mouse pointer will move up and down. same for horizontal movement.....

A rock drill is exactly what the name suggests. They are either pneumatic ( air driven) or electric ( smaller applications) and are used to drill holes in rock for any number of reasons. Usually used in construction. In mines, they are used to make the cavity to house the TNT for detonation.

The basic theory is that if you pump steam into a place where there is a piston, the piston will move up.  Then you release the steam and the piston will go down.  You connect the piston to something to get movement, such as some gears that turn the propellers or connect them to the wheels.  It's a bit more complicated than that, but that's basically how it's done.

The pneumatic tubes will only allow it to lift; in order to rotate (that is a different degree of freedom) you will need something like a rotator cuff.

I'm not 100% familiar with this but this should be pretty close to the answer.  Simple/standard crane motors work by applying power first through a rotating steel shaft into a gearbox.  The gearbox allows the gearing ratio to be changed (to trade rotation speed for torque or torque for rotation speed).  Another steel shaft carries the power out of the gearbox, again through rotation, to a spindle (think big thimble) around which steel cable is wrapped.  So the motor rotates this spindle to wind in the cable or unwind the cable to lift things or lower things.\n\nHere is a good page on cranes:\nhttp://en.wikipedia.org/wiki/Crane_%28machine%29\n\nHere is a good page on motors:\nhttp://en.wikipedia.org/wiki/Electric_motor

the is rotated in the magnet with the help of the wheels which are turned by the driver. this induces electricity to flow through the wire. this electricity is used to light the bulb.\nlook up electro magnetic induction.

A separate device, based on something like a drilling power tool, is used to spin a special axle in the rear of the car, which is connected to the gearbox and to the engine; spinning it at a certain speed spins the axles at that same speed and kick-starts the engine. There is no such thing like an ignition key.

Okay... If ur serious then I'm game!!  The piston is attached to the piston rod.  When the rod is pulled down by the crackshaft, kinda like bicycle pedals.. the piston draws air into the cylinder.  Then the crankshaft pushes the rod and piston up causing compression.  Then the spark plug ignites and blasts the piston and rod back down creating power.  Then the crankshaft pushes the rod and piston back up expelling the waste.  The piston is the 'plunger' of the system, kina like the black rubber plunger in a hypodermic needle.

The Phillips screwdriver was invented believfe it or not by a man named Phillips in the state of Oregon. I don't know the patent #.

Works Great!!!\n\nThere are numerous sites that explain how they work but can get complicated if you do not understand the "Geek" terms.\n\nWell a printer is sort of a different animal of its own.  All hardware, peripherals, etc. all require "Drivers" which is software that controls the device for which it is intended, more or less the "Boss"\n\nLets say you were building furniture that will need boxed up and assembled by the purchaser.  When you are finished building your project you "Print" it or send the project to your "Boss" for verification.\n\nThe boss recieves this and all the pieces are separated into equal packets along with a set of instructions that contains step by step how to build the product (all info sent will be margins, colors, sizes, etc) to make it easy for the purchaser (Printer in this case) to locate the parts.\n\nThese packets are then sent to the purchaser in the order they need to be assembled to yield the correct item.   The purchaser (printer) looks at these instructions in each packet and follows them.  Its print head will be like you looking at the directions and saying I need to put this screw in first before I put this part on.  So in other words the print head is like a set of hands completing the final output.\n\nHope this helps a bit without being soo technical.

there is either a pad where you slide your finger across\nor \na little ball knob thing which is controlled through pressure and direction of one finger pressing it.\nYOU CAN allways hook up a mouse through USB port
