post heating : after completion of weld is not cool below to preheat or room temp. further it is heat by applying addition heating system to certain period of time and temperature to evalute hydrogen from weld metal.

An autogenous weld is one where filler metal is not used for joining.

the weld is produced by fusion of the parts by melting.

It does not use force to bond the parts, only the heat produced which cause melting of the base materials.

I am not for sure if all of them are but my f-250 has a aluminum turbo fan. I am pretty sure all fans would have to be made out of a light material maybe even plastic on some little turbochargers.

As you are aware an HSS tap is so hardened to cut thread in different materials. When hardness of HSS increases lead to sudden failure as it will be brittle. If we cut a thread in its first pass the tap will experience heavy force lead to breakage of tap. In order to reduce cutting pressure the taps are so designed to share the cutting depth hence cutting force. Hence the taps are of First, Second and final cut taps marked with one, two and three rings on its shank to identify it.

A tensile test machine is designed to give a straight line pull on a member so that it measures only direct tensile stress given as the force applied divided by the member area

Chainsaws use a mixture of 80% petrol and 20% 2-stroke oil. You can buy it already mixed, or (more commonly) mix it yourself.

No, you can hide it but can't remove it.

it will as it is connected to your wheels

Since water does not burn, any moisture in the combustion air will simply be heated by the fire. Since water has a large heat capacity, this results in wasted energy. The drier the combustion air the more efficiently the burner will burn.

There isn't a 5.7L Hemi diesel.

What does it cost to build a wind turbine? Capital costs for wind projects are $1,500 - $2,000 per kilowatt of nameplate capacity. How does the cost of wind energy compare to other energy sources? Wind-generated electricity has become more economical to produce in the past 10 years, dropping from as much as 30 cents per kilowatt-hour to 4.5 to 7.5 cents, making it more competitive with other energy sources. The cost to develop and build a wind energy facility is approximately $1.3 million to $1.7 million per megawatt, compared to a cost for gas-fired energy generation of $800,000 per megawatt.

Supernatant is the clear fluid above a precipitate or sediment. Pellet is a small rounded object, ball, or spherical body.

10-100 USD depending on condtion.

a standard chest tube is a hollow tube that inserts into the chest's pleural cavity. a trocar is a metal rod that's inside the chest tube, some doctors prefor the trocar for easier insertion through the intercostal muscles.

When referring to size, something can be very small or very big. When referring to the shape, an item can be round, square, or even a triangle.

It increases the time taken for the force from the impact to be distributed to the passengers so the overall force is decreased. It relates to newtons first law about the acceleration of objects.

You see and hear water flowing out of it's drain tube into the floor drain.

About 7750 grams to 8050 grams depending on the type.

to let the steam pass and avoid an explosion under some undesireable circumstances.

For a passenger car it takes about 25 minutes to manufacture 1 tire. This includes both vulcanization and curing processes. For larger off-road or truck tires it could take up to 24 hours or longer to produce a single tire. Its the curing process that takes the most time. The vulcanizing process only takes 10 minutes for a passenger car tire but increases by some minute the larger the size of the tire.

As the piston rises it compresses the fuel-air mixture and simultaneously sucks fuel and air into the crankcase. A little bit after top dead center, the spark plug fires the compressed mixture forcing the piston back down. As the piston travels down, it uncovers the exhaust and intake ports. The fuel-air mixture in the crank case is forced into the cylinder and blows most of the exhaust gas out by the time the piston starts upwards again and covers the exhaust port. The piston continues upwards to compress the fuel-air mixture and the next cycle starts.

There is a very nice animation at the link, below.

Megatronics is the technical discipline of creating electronic systems that take up as much physical space as possible. An example is creating a computer that takes up an entire room, to do simple arithmetic. Another example is making the servers that run the Internet large enough to fill the core of the Earth. Megatronics is very popular in Texas.
