The displacement is proportional to the strain. This does not factor for creep and time.

Governor is a device used for maintaining a constant speed of rotation of the crank shaft over long periods during which the load on the engine may vary.

it is good accurate and high dimintional

Psig (pound-force per square inch gauge) is a unit of pressure relative to atmospheric pressure at sea level. By contrast, psia measures pressure relative to a vacuum (such as that in space). Most pressure gauges, such as tire gauges, are calibrated to read zero at sea level, because most applications require the difference of pressure.

At sea level, Earth's atmosphere actually exerts a pressure of 14.695948804 psi. Humans do not feel this pressure because internal pressure of liquid in their bodies matches the external pressure. If a pressure gauge is calibrated to read zero in space, then at sea level on Earth it would read 14.695948804 psi. Thus a reading of 30 psig on a tire gauge, represents an absolute pressure of 44.695948804 psi.

^^^ The last sentence assumes a greater level of precision than could be obtained from most standard tire gauges. If we assume that 1 psi can be distinguished on the gauge, then the absolute pressure would have to be expressed as 45 psi.

Degree of reaction can be defined as the ratio of pressure energy change in the blades to total energy change of the fluid..

For eg If we have 50% KE and 50% PE then the degree of reaction is 0.5

I am not sure that it is more common. The large welding rigs that are mounted on trucks mostly use DC, but they can be set for AC. If the question is based on a survey of the cheap welders at a retail outlet, the answer would be that AC welders are simpler to make, since only a transformer is required to change the voltage. A DC welder needs to convert the power from AC to DC, which is more complicated and therefore more expensive. Cheap welders may be easier to sell to a beginner, therefore more of the welders would be AC.

An angle stop is not intended to control water pressure for most applications. That being said, however, you can control the pressure with an angle stop valve (Aka angle pattern globe valve) while there is flow. As soon as the flow stops, then the pressure will equalise throughout the system.

I would suggest using a PRV or pressure reducing valve. This will control water pressure under most all conditions.

Limit gauges can be designed to check a single distance, length or diameter, or may serve the inspection of multiple dimensions. This later may comprise contours, a combination of contours and length dimensions, geometric forms individually or combined with length, such as tapers and cylinders, or the interrelation of several forms, sizes and their location on a single body or within a assembly.

the bell crank lever is a apparatus used to verify the law of moments.

Levers allow you to manipulate heavy things with less force, at the cost of more distance traveled.

128 psi = 8.83 bar

Bleed air in gas turbine engines is compressed air taken from within the engine, after the compressor stage(s) and before the fuel is injected in the burner

well, the formula for working out volume of a cylinder is PiR^2

which means pie times the radius squared, that gets you one face then you times that by the length so the forumal is R

pR2xL where R is the radius and L is the length.

Or

Volume= Bh

B= the area of the bases

h= the height

Cooling energy depends on the efficiency of cooling device used but cooling load depends on many factors such as the volume of the room, comfort band, fabrics used, geographical and climatic properties of location that the room is built.

In simple terms, for a room with a specific cooling load different devices can be used. Since, each device has different efficiency, therefore different amounts of cooling energy may be obtained.

We tend to use them to mean the same thing.

In two dimensions, a simple support is one that allows rotation. A pin joint support is a simple support that allows rotation but not translation. A roller joint support is a simple support that allows rotation and translation.

Angles that add up to 180 degrees

this cannot be answered metres per second is a velocity, units ms-1, litres per second is a volumetric flowrate, units dm3s-1 you would need the area through which the 'velocity' is flowing to answer that otherwise, litres is dm3 = m3 x 10-3

Sonic technology is technology that utilizes the power of sound waves. This is seen most often for consumers in the form of sonic toothbrushes that use focused sound waves to create faster vibrations forÊthe brushes.

A belt drive is an alternative to a chain drive (as you would normally find on a bicycle or motorcycle). There are several types of belt used in belt drive systems including V-belts and toothed belts. The more common is the V-belt. A cross section of the pulley used shows that the belt runs in a V-shaped groove. Washing machines, older cars, and machinery use this type of belt system. The toothed belt is normally wide and flat with teeth on the inside to prevent slippage. Harley Davidson motorcycles use these, as do super-charged engines in cars.
