How does a tire pump work?
405618
the tire pump valve fits so tight over the nozzle and combine with push air in keeps air from escaping. also, air wil;l not come out of a tire ( unless a leak) unless you twist the nozzle to make it come out

any movement thru a fluid produces static electricity.\nDriving(movement)+ Air(fluid)=Shock.\n\nThe tires insulate the charge from going to ground until you touch it. You are then the conduit to ground.

Sure! Remove the tire from a driving wheel, block the other from turning. attach a magnet to the wheel/rim so it wont fly off. Wind a few dozen turns of insulated wire around a bolt and fasten it to something that will hold it near the magnet as it passes by. With an a/c voltmeter  attached to each end of the coil as the magnet goes by you will observe a pulse of voltage each time the magnet goes by.\nDON'T OVERDO IT YOU CAN GET HURT.

An example of this is when the air is released from a pneumatic tire; the outlet air will be noticably cooler than the tire, and after all the air has escaped the valve stem will be cold to the touch. Diesel engines rely on adiabatic heating during their compression stroke to reach the high temperatures needed to ignite the fuel. Such temperature changes can be quantified using the ideal gas law.

Mechanical jacks are classic levers (fulcrums).  You apply a lesser force through a longer distance on the input in order to achieve a greater force over a lesser distance on the output.\n\nHydraulic jacks are based on the property of non-compressibility of liquids and uniform pressure throughout a static liquid.  You apply a given force to a small area on the input (the pump) which transfers that pressure to a larger area (the piston) thus amplifying the force (but again, reducing the distance).

It's difficult to explain without diagrams.\n\nFirst you have an air supply at about 20 psi that flows through a restrictor and a small nozzle the same size as the restrictor. There is a flapper, a small piece of metal that covers the nozzle and controls the backpressure between the nozzle and the restrictor. The pressure between the restrictor and the nozzle is controlled between 20 and 100KPa (3 to 15psi) by the position of the flapper. The position of the flapper is controlled by the input current (usuall y 4 to 20mA of 1 to 5V). Thus the input signal varies the pressure out. I havent seen any links but I will look

Deflate the tires a little bit so that the truck has a small amount of clearance and can drive underneath it

The simplest explanation I know is in terms of the instant center.  We all think of a wheel as rotating about its axis.  That is true, relative to the tricycle frame.  However, relative to the ground, the axle moves forward.  The point where the tire touches the ground is stationary.  It does not move with respect to the ground.  An instant later, another part of the tire is touching the ground and again, for an instant, that point on the tire is stationary.  \n\nOn any rotating body, the spot that does not move (it may rotatebut not translate) is the center.  At any instant, the part of the tire touching the ground is not moving and is, by definition, the instant center.  The wheel is rotating about this instant center.  SInce the pedal is above the instant center, your forward horizontal force rotates the wheel forward.\n\nYou can prove this all to yourself by trying a few things with the string on the pedal.  Instead of pulling horizontally, raise the angle of the string.  When the line of action of the string passes through the contact point between the tire and the road, you will find that pulling on the string will not rotate the wheel.  If you pull hard enough the trike will move but the front wheel just skids.  Since the line of action of the applied force is passing through the center of rotation, there is no torque to spin the wheel.\n\nRaise the string higher and the trike will roll backwards because the force is acting on the other side of the center creating a torque in the opposite direction causing the wheel to turn the other way.   \n\nIf you don't have a trike handy, you can do this with a spool and a string.  Just wrap the string sround the spool with the end coming off the bottom of the spool.

Follow the steps with reference to the webpage ...\n\nStep 1 Characteristics of air\n\nLet's fit a rubber to a can like Figure 1. You can understand easily that the rubber expands when the can is heated (Figure 2), and the rubber contracts when the can is cooled (Figure 3). It is caused that a pressure of the air in the can works to the rubber when the air is heated, shown in allows of Figure 2. Of course, you cannot see the pressure by your eyes.\n\n \nStep 2 What is a displacer piston?\n\nNext, let's put in a piston into the can like Figure 4. A diameter of the piston must be somewhat smaller than that of the can, because the piston works to move (displace) the air up and down in the can. And, please heat the bottom side of the can and cool the upper side of the can. After it has enough temperature difference, move the piston up and down by your hand. When the piston is moved up, the rubber expands because there is a lot of hot air in the can (Figure 5). It corresponds to Figure 2. When the piston is moved down, the rubber contracts because there is a lot of cold air in the can. It corresponds to Figure 3.\nIn the case of the Stirling engine, this piston, which moves (displaces) the air and make the pressure changes is called a displacer piston.\n\n \nStep 3 Crank mechanism ~ from piston motion to rotation ~\n\nDo you understand about the characteristics of the air and the work of the displacer piston? They are very important to understand how does the Stirling engine work.\nFirst, connect from the piston and a bent wire with a thread like Figure 6. When the bent wire is rotated, the piston is moved up and down. This is called a crank mechanism.\nPlease heat the bottom side of the can and cool the upper side of the can, similar to above description. When your hand rotates the bent wire, the piston is moved up and down, and the rubber expands and contracts repeatedly (Figure 7).\n\n \nStep 4 Power piston ~ function of the rubber ~\n\nThe Stirling engine converts from the motion of the rubber to the rotation of the bent wire. Please connect from the rubber to the bent wire with a rod. In this time, a force of the rubber (expansion and contraction) has to be the direction, which rotates the bent wire. In short, you must bend the bent wire the just right angle (90 degrees) from the piston like Figure 8 and 9.\n\n \nStep 5 Flywheel ~ for the smooth rotation ~\n\nThis engine has not worked yet. If you try to work this engine (Figure 8 and 9), the rubber keeps the most expansion or contraction. In order to rotate smoothly and repeatedly, you must fit a rotated mass with the bent wire. It is called a flywheel.\nGenerally, the flywheel is circular like Figure 10. But at this point, please bend the end of the bent wire, and fit a mass at the edge of the wire like Figure 11. The mass works as the flywheel and to be balanced to the weight of the piston. So, you must fit the mass against the piston.\n\nThis page of diagrams courtesy of Koichi Hirata.\n\nPlease click the link for the diagrams ...\nhttp://www.hotairengines.com/WorkingDescription/Work.htm\n\nWith Love\nsridhar

One which is not interrupted. This can be done with a reserve tank, for example, as in an "air hose". It can deliver a constant supply of air, from the reserve and then ,as the pressure begins to dissipate, the pump comes back on, keeping the supply constant. The pressure in the tank is maintained at a higher level than at the "regulated" out put.

there is a hole in the end of the nozle.when that hole fall below the gas line, pump senses stop of air flow and stops pumping gas. (when you pump gas in you are also pushing air out.) Thats why if you pull the nozzle out some you can get more gas in. You are moving the hole above the gas line.

You need to fill in more information.  There are many kinds of pumps, two major classes being positive displacement and centrifugal.  Traditionally, something like a swimming pool centrifugal  pump could never be reversed so power would be produced by forcing fluid through it.  So in that case, the pump cannot be used as a turbine.\n\nIf you take a positive displacement pump, like a roots-type blower (supercharger), you CAN run that in reverse and blow air in one end and get shaft power out.  \n\nHydraulic motors used to turn wheels slowly on construction equipment can also be used as pumps--they will work either way.  If you apply shaft power, you will get fluid power out.  If you apply fluid power, you will get shaft power out.  \n\nTurbine pumps are usually very specifically designed to run only in one direction and have shaft power going into them rather than out.

well, i cant really explain it, but you can use rubber band or a mousetrap to power the car. if u google "mousetrap car" or "rubber band powered car," you'll find diagrams and steps on how to make it.

You mean for like a dispenser?\nComercial electric cream dispensers use a hose that comes integrated with the bag that the cream comes in.  You put this hose inside a wheel mechanisms that has bumps on it, as the wheel spinks slowly the bumps squeeze the rubber hose for a short length of the hose, and thus pumps cream out.  This can be applied to milk too.

Answer to the first part of thequestion;  \n\nConsider a water tank full of water.We connect a pump which pumps the water from the tank and delivers it again to the tank. \n The tank will never be empty and the water will be flowing continuously along the pipe connected to the pump and tank.\nIf the pipe connecting the pump and tank has an obstacle say a solid block of wood  which is somehow inserted into the pipe, then there will not be flow of water. But still the pipe and tank will have water but with out  any flow. \n Similarly in an electrical circuit electrons are like water in the tank ;the wire is like the pipe; the battery or cell or generator of electicity is like the pump in our example.\n Electrons flow from one end(tank) of the battery(pump) to the other end (tank) through the wire like water through the pipe.\n If one end of a wire is connected to the battery and the other end is left free,we have to imagine that the free end is further connected to the battery by an imaginary wire made of air.( The only matter that connects the free end to the battey is air) Just like water cannot flow through the wooden obstacle electrons cannot flow through air. Though the wire is full of electrons there will not be any flow of  electrons. \n\nAnswer to the second question,'Y dont they fall when they reach the end.\n\nThe wire is full of electrons even if there is no flow. We shall lift one end of the wire and let  the other end loose. It is natural to expect all the electrons in the wire to fall down due to gravity. But the electostatic force beeing very much stronger than the gravitational force keeps them within the wire. To remove them out we must apply a force atleast equal to the electostatic force. The function of the battery, in fact ,is  to provide such a force.
