aluminum is cheaper, however it has also been shown that those afflicted with alzheimer's had high levels of aluminum in their brain tissue. whether there is a link or not, we do not know. however, i am going the route of stainless steel for that reason

An atomic orbital is a mathematical term signifying the characteristics of the 'orbit' or cloud created by movement of an electron or pair of electrons within an atom. Angular momentum, signified as l, defines the angular momentum of the orbital's path as opposed to values n and m which correspond with the orbital's energy and angular direction, respectively.

This depends on the type of stainless steel. I've seen stainless steel 303 with <=0.15% carbon, which I think is typical.

If you have a specific type of stainless steel that you want to know the carbon content for you can get a pretty good idea by using matweb.com

compasses have Mineral Oil filled Needle Housings, with steel needles that pivot on a sapphire bearing

The light mineral oil is there to damp the needle (stop the needle swinging too loosely) and it has to withstand freezing (because compasses are used in cold places).

your the are wedges do you see how you bit down and open them that's is because of the wedges in your mouth

try this website it might help - http://www.engineeringtoolbox.com/beams-support-forces-d_1311.html first off the calculations are based on beam size (example w14x26 [14=14" x26=lbs. ) which is around 5 3/16" wide x 13 7/8" high the flange thickness is around 3/8" thick and the web would be 1/4" wide you also must check the span and application (concrete Pier's, or schedule 40 columns (1/4" thick steel column) there are other factors which are involved in other words consult your engineer

GP pipe and GI pipe are both types of galvanized pipes, but they are made in different ways. GP pipe is made by electroplating zinc onto thin sheets of carbon steel, while GI pipe is made by dipping the steel sheets in a molten bath of zinc.

GP pipe has a smoother finish than GI pipe, which makes it more resistant to corrosion and rust. However, GP pipe is also more expensive than GI pipe.

GI pipe is less expensive than GP pipe, but it is not as resistant to corrosion and rust. GI pipe is also more likely to have a rough finish, which can make it more difficult to clean.

Which type of pipe is right for you will depend on your specific needs and budget. If you need a pipe that is highly resistant to corrosion and rust, then GP pipe is the better choice. However, if you are on a budget, then GI pipe is a good option.

Here are some additional uses for GP and GI pipes:

Water supply: GP and GI pipes are commonly used for water supply lines, both underground and above ground.

Drainage: GP and GI pipes are also used for drainage lines, both indoors and outdoors.

Plumbing: GP and GI pipes are used for a variety of plumbing applications, such as sewer lines, gas lines, and vent pipes.

Construction: GP and GI pipes are also used in construction, such as for rebar cages and formwork.

Used for Oil Pumps and stuff.

A "smart material" is one having a molecular structure that responds in a particular and controlled way to influences upon it. These range from magnetically-changed materials, to "memory" molecules that return to their original form, to materials that generate an electric charge when pressed, twisted, or warped.

These materials can significantly change their mechanical properties (such as shape, stiffness, and viscosity), or their thermal, optical, or electromagnetic properties, in a predictable or controllable manner.

Some types of smart materials are piezoelectrics, electrostrictors, magnetostrictors, and shape-memory alloys.

HI!!!!
check out my answer....

The difference between the two is....

The plastic deformation will occur where pressures are relatively high and the strain rate relatively low. During plastic deformation, the materials flow and changes in shape will be permanent. While,

The elastic deformation will change shape in response to a stress, then snap back into it's original shape if the stress is removed. (in other words, the strain is recoverable)


IN short word...THE PLASTIC DEFORMATION ARE PERMANENT AND THE ELASTIC DEFORMATION WILL GO BACK TO ITS ORIGINAL SHAPE.

Mechanical engineering covers a wide range of possible degree's based on what exactly you are going to specialize in. I would suggest looking to the colleges that are available to you and the accrediting they have because choosing which school to go to. Also, ask a few places that specialize in mechanical engineering and see if one school would look better to them.

Weight is sensed using a transducer. A weighing machine transducer is usually a spring/piezoelectric component. The resistance of it varies as the weight changes. So does the current through it. This current is sensed, and is converted suitably to output it's weight.

The energy stored in a spring when it is compressed or expanded. See related link.

A lathe machine is a heavy duty and high powered tools largely used in engineering. They are used to cut and shape metals, woods or plastics and even drill holes with added parts. There are different kinds of lathes used in engineering depending on what the job is, such as mechanical engineering.

Both use the pressure difference caused by air moving over the wings at different speeds to generate lift; a plane by moving those wings in the direction of travel, a helicopter by spinning the "wings" around at high speed.

This requies that the plane be in constant forward motion in order for the wings to make lift. Thus airplanes must roll along the runaway to take-off. A helicopter cant take off at zero forward speed and hover at zero forward speed. The helicopter can land and take off vertically. Thus, they are good for landing in unimproved spots such as done by air ambulances.

The Diesel cycle engine was named after the German engineer who invented it, Rudolf Diesel. A Diesel engine uses two principles: air gets hot when you compress it, and fuel will ignite if it gets hot enough. The engine compresses air introduced into the cylinder to a very high pressure. When fuel is injected it immediately ignites.

Welding, like any other skill, is one that requires practice. Once you know the basics and have a few hours of practice, you should be able to run a simple bead on an easy metal like steel with most arc welding processes. Wire welding is usually the easiest to learn. However, you shouldn't expect greatness after a few hours. Like most things, your welding skill will improve with practice.

The chemical composition of 420 grade stainless steel is:- Chromium: 12-14 %-Silicon: max. 1 %- Manganese: max 1 %- Phosphorus: max. 0,04 %- Sulfur: max. 0,03 %- Carbon: min. 0,015 %

Eugene Bourdon 1849 France measures the preasure of liquids and gasses

yield strength = 235 MPa (as implied in the name)

tensile strength = 375-460 MPa

See the related link for further information.

Note that the main difference between different grades of Q235 (e.g. Q235A vs. Q235B) is the impact strength. Q235B has better impact properties than Q235A.
