Engineering

The working conditions vary for a mechanical engineer depending on his job. Most positions are salary so the hours range based on the project you are working on. I've worked 30 hours one week and 60 the next. Most of the time your company will only want you to work about 40 hours a week.

Physical conditions for Mechanical engineering can be anywhere from a sit behind a computer doing sales consulting or CAD drawings, or it could be field work, where you are outside inspecting or repairing equipment. I depends on what field you find a mechanical engineering position in. When looking for a job, I got offers from working on a oil rig in the Gulf of Mexico to doing aluminum window designs in AutoCAD. No matter what your personality, there are job conditions that can fit what you are looking for. The best way to get them though is experience and that takes time.

Creep usually occurs as a result of thermal and physical stress overcoming the elasticity of the metal preventing it from returning to its original shape after the stress is removed.

A three-phase 'unbalanced' system refers to the load, as the supply voltages are unaffected by load. So the phase-angle and, therefore, the power factor of each phase will be different -i.e. there will be three different power factors.

There are 4 basics to producing a good weld bead.

Correct

#1 Amperage #2 Electrode Angle #3 Arc Length #4 Travel Speed

Factor in electrode manipulation in some cases.

A welding machine rated at 500 amperes uses around 120000 watts of power. This is used in very heavy industrial applications due to its large power draw.

An adapter, depending on what device your using it for connects that device to the internet or a network.

They could be made of steel, plastic, they've even been made of wood in the past.

Using Ohm's Law. It is 2.5 volts divided by 5.0 ohms which is 0.5 Amperes.

A marine biologist is a scientist. They study the Biology of marine life. The specific cluster would be a scientist - Biology - Fisheries.

Of course as with all fields of science the cluster could be narrowed down even more or expanded to just science.

It is used where cost is a big factor but high strength is still required.

An altimeter does not actually measure altitude directly, but rather just atmospheric pressure. So an altimeter is actually a barometer created for a specific purpose.

See related link The altimeter measures the height above the ground and has a pointer which is adjustable depending in which air field you are taking off on. it measures the pressure of the air as you get higher off the ground the pressure reduces therefore it is able to determine your height above ground.

I presume that the box is more than "square", that it is in fact a cube - 1 metre along all sides.

The volume of such a box is 1 cubic metre.

The area of the base of such a box is 1 square metre. If the height is anything other than 1 metre, multiply the height in metres by 1 and you will get the volume in cubic metres.

A fathom is a nautical measurement equal to 6 feet.

The surface pressure of the earth is nominally 1013.25 hectoPascals (hP), which is also referred to as 1 ATM (1 atmosphere).

The surface pressure of the earth will vary slightly according to weather conditions.

In most universities, it's because it's a first year requirement, but in some disciplines like software engineering and electrical engineering, you will be programming, testing, and inventing new software and write reports on it.

AC current will 'hold you' and DC current will throw you clear if shocked. Don't touch anyone if you witness them being shocked - kick them clear in a karate style or use a broom, something that won't conduct. In any event, AC or DC, a unit that can shock you is extremely dangerous and should be unplugged and the leads cut off.

By accepting reviews on a design project, whether in digital or physical medium, a designer can take critique/feedback on their project.

This critique/feedback can possibly affect the designer opinion of what looks good, and then the designer can work on the project to reach what they would consider an improvement.

still this might not be seen as an improvement to others, at which point we get into a philosophical discussion on who's point of view is correct. No one can answer that question so lets not try to.

Generally it is put there to keep animals from climbing up the trees. Squirrels for example, will eat all of the nuts and fruit out of a tree. If you put up sheets of metal about 4 feet off the ground, it will keep them from being able to climb up.

Chenab Bridge, under construction in 2014, will be the highest railway bridge in the world. Standing 359-meters tall, and 1,315-meters long, the bridge is located between Bakkal and Kauri in the Reasi district of Jammu and Kashmir, India.

This question is incorrect; engineering is as suitable for women as it is for men. While most engineering workplaces are male dominated, that doesn't mean that women can't do the work just as well. However, women wishing to go into engineering should be prepared to deal with the stereotypical view that engineers are men.

The lowest frequency of an LC low-pass filter is zero, i.e. DC.

Force is very important. First of all because it makes the world go round! Second, because without force we would fall of things because force pushes or pulls us back. For example, when we sit on a chair, we need force to push us and hold us so we won't fall.
