This question probably is referring to a 2% secant modulus, which can be the tensile, flexural or compressive modulus (slope of a stress/strain curve) of a material that is determined from calculating the slope of a line drawn from the origin to 2% strain on a stress/Strain curve.
When cutting skirting how do i dissect an angle that isn't 90 degrees?
you have to use a metrsaw, if it is not available use jigsaw just make an accuracy in measurement. with Handsaw it is easy but take much more time and your power :)
There isn't a way to answer this question because of the variation possible in the different beam shapes. Web and wall thickness can vary greatly, even if we throw out an arbitrary "standard" like making all the beams equal in cross-sectional area. No way this is gonna be testable in any lab. The engineering director would kick you out and tell you to write some standards for comparison. We can make a few statements that shed some light on the difficulty of the problem. A single beam is under stress just by its weight, and with a live load, the different types of stress increase. There are a number of different forces acting on the beam, and beams of different shapes will react differently to the same loads, whether they be static, live or dynamic. Different steel shapes are used in different applications to take advantage of the strength characteristics of those different shapes. For instance, in a standard I beam, the majority of the loads are carried by the top and bottom flanges and the strength of the beam is increased as the web depth becomes greater. Links are provided, and it will be helpful to just skim the introductory parts of the articles. Going completely through the posts with understanding requires some pretty heavy duty math knowledge.

Do air conditioners extract the cool air from the atmosphere as part the cooling process?
That's one way to look at it.
When a refrigerant is compressed it still contains the same amount of heat energy (don't confuse that with temperature, that's something else altoghether) that it had BEFORE it was compressed and since the volume is smaller, the temperature goes up. The state change (gas to liquid) also gives off a lot of heat, but don't let that part confuse you. The compressed (and heated) refrigerant is then passed through a coil of tubing and the heated refrigerant is cooled by the ambient air completing the gas to liquid state change.
Then the compressed refrigerant passes through an orfice (a restriction in the tube) and is allowed to "flash" back to a gas. Now it's at a much lower pressure and the volume of refrigerant now contains much less heat (again, not to be confused with temperature) that it did when it was a liquid. Another part of the process is referred to as the "heat of vaporization", which really cools things off, sort of like the cooling from sweat when you get hot.
But it's all a balance, since the cool air that was generated for the INSIDE of your car or house eventuall leaks out to the outside air, resulting in a net zero effect.
Little transformers which convert the 240 volts supply voltage to 120 volts are readily available. They are called International Travel Adaptors. One of those would probably be able to handle the small current needed by the 18 volt battery charger. == == This question is too complicated to answer fully without using lots of electrical engineering words that many people would not understand. If there is something that looks like a transformer on the circuit board, it may not be one. It might be a miniature inductive load. (A "choke" in old times terms.) Even if it is a miniature transformer it may not be used for changing the mains voltage to 18 volts. Someone who really understands electrical circuits and the components in them would not be asking this question, so, unless you know exactly what you are doing, leave that charger's circuit board just as it is. This is for your own personal safety and for anyone else who might one day use that battery charger.
What is the difference between kiosk and a vending machine?
The kiosk is a booth with a computer. For example, you can see them at stores whereby you can fill-out a job application. The vending machine is is filled with items you can purchase.
yes they can be melted down and made into many other things, like lumber, park benches, and plywood. here is a link for more info. http://www.myplasticbag.ca/main/default.php?id=1295
What does steam do to a turbine?
Steam (under pressure) comes into contact with the blades of the turbine through which it is flowing and, by the direct application of force, causes the blades to move, turning the turbine shaft. The turbine coverts the thermal energy of the steam into (rotating) mechanical energy. Surf on over to our friends at Wikipedia using the provided link and get more info. Oh, and check out the pics! Answer it depends what type of turbine one is using
types of steam turbine
1 impulse turbine 2 reaction turbine in 1 st one steam is completely expanded inside nozzle and all pressure energy get converted in to kinetic energy using this impulse force turbine runs.
in 2nd steam is multiple stage blades are used where high pressure superheated steam gets expanded inside the turbine in each stage and after each stage velocity of steam increases.
very high temperature superheated steam is reaquired because it has very high specific volume which helps in reducing mass flow rate of steam.
What is the minimum radius applied in sheet metal forming?
the industry standard is a minimum of twice material thickness. however, four times is better for thicker materials as this helps avoid stress cracking.
air vessel is a closed chamber containing compressed ait at the top portion and liquid at thw bottom portion of the chamber.At the base there is a opening through which the liquid may flow into the vessel or flow out of the vessel.
FUNCTIONS:
1) Obtain continuous supply of liquid at uniform rate.
2) To run the pump at high speed.
A load chart....is a chart usually found on the arm of a crane. It shows you how much the machine is rated to lift at specific points of the lift under ideal conditions. In equipment with telescopic booms; the weights that it can lift varies ( the further you have to extend; the less weight it can bear), as well as turning radius under load also varies. The more you turn your crane under load the less stable your crane can become causing it to topple over if you don't abide by the chart and try to lift more then it's rated capacity. Although a load chart is the most important chart you must understand before operating a piece of machinery such as this, it does not take into account other factors that can effect a load such as; wind speed, condition of the equipment, how to rig or sling a load, or any other deciding human factor. Take a crane course before messing with this kind of equipment. Learn how to read a load chart properly. your life is worth more then the equipment that could topple over and kill you.
Can you have too much water pressure in a residential house requiring a pressure release valve?
The water pressure in my house is about 140PSI. Which is definitely dangerous. It happens more often than you would think. What happens is a city will use water supply lines which are too small for the water requirements. Therefore, they have to increase the pressure. You wouldn't want a pressure relief valve, because then if the pressure was too high, it would just spray water everywhere to release the pressure. You would want a pressure regulator installed, which is what I am working on for my house right now. Just to let you know though, you may have to get a thermal expansion tank for your water heater if you don't have one. See, the new pressure regulators have a check valve in them, which prevents water from traveling back into the city pipes once it has gotten into your house. When your water heater heats the water, the air bubbles in it expand, which increases the water pressure, and will probably cause your pressure relief valve on your water heater to blow.
You can get a cheap water pressure meter at any improvement store to check it out. 50-60 PSI is ok. I would say you could take it up to 70 or 80 PSI safely.

How do you install an ignition switch?
Unfortunately, that's a really hard question to answer because I don't know what kind of car you have. If it's an older car with the ign. switch in the dash you simply unplug the wires, remove old switch and install a new one in reverse order. If however, you're talking about a switch in the steering collumn... those can be tougher. Basically though, you pull the wheel, possibly remove the wheel locking mechanism, pull the ign. switch (key) retaining screw or pin and remove the lock. Assemble in reverse order. However, however, however, if you're actually talking about the electrical end of the ignition switch in a steering collumn... Ugh. Forget it. Those ones are monsters. For professionals only. You usually gotta tear the whole collumn apart.
Hope that helps a little.
Why does an F150 with a 302 stall when starting changing gears or turning corners?
My guess would be the fuel pump. I dont know how to change it, because i havent had to replace the one on my truck yet, but i would guess the fuel pump.
How does a bicycle tube valve work?
Bicycle tube valves are one-way valves. They let air pass one way, then holds it in.
What is an airspeed indicator?
An airspeed indicator is an aviation instrument which displays an aircraft's current airspeed.
Why thrust reversers instead of aircraft braking system?
Thrust reverser systems are featured on many jet aircraft to help it slow down just after touch-down. This reduces wear on the brakes and enables shorter landing distances.
Is a isometric projection used for developing a multiview drawing?
No, a multiview projection is used for developing a multiview drawing. Multiview projections are orthographic projection where the object is behind the plane of projection, and is oriented such that only two of its dimensions are shown.
What is the name of a pushing force?
In physics, there is no special distinction - no special names to distinguish - pushing forces from pulling forces. Of course, you can simply call it "a pushing force", if you want to make such a distinction.
