Mechanical engineering is one of the broadest engineering disciplines. Mechanical engineers research, design, develop, build, and test mechanical and thermal devices, including tools, engines, and machines.
Important : These are some basic guidelines and tips.
The entropy of the universe increases over time and moves towards a maximum value.
Normally galvanized pipes are not used for steam. Mild steel with screwed or welded fittings are the norm. Pressure and temperature are very important factors to be considered in what type of materials to be used. Steam even at low pressures can be extremely dangerous.
The shear center is the centroid of a cross-section. The flexural center is the center of twist, which is the point on a beam that you can add a load without torsion. The elastic center is located at the center of gravity. If the object is homogeneous and symmetrical in both directions of the cross-section then they are all equivalent.
A projectile has no motor/rocket on it, so all of its momentum is given to it as it is launched. An example of a projectile would be pen that you throw across a room.
A rocket or missile does have a motor/rocket on it so it can accelerate itself while moving and so resist other forces such as gravity.
Stay away from a specific job. You cannot win. If you say the job you are contending for is it, you strain credibility. If you say another job is it, you plant the suspicion that you will be dissatisfied with this position if hired. The best is to stay genetic and say something like A job where I love the work, like the people, can contribute and cannot wait to get to work.
Specifics here are not good. Something like this should work. I would like it to be a long time. Or As long as we both feel I am doing a good job.
This may take some thought and certainly, should be based on the research you have done on the organization. Sincerity is extremely important here and will easily be sensed. Relate it to your long term career goals.
A loaded question. A nasty little game that you will probably lose if you answer first. So, do not answer it. Instead, say something like, That is a tough question. Can you tell me the range for this position. In most cases, the interviewer, taken off guard, will tell you. If not, say that it can depend on the details of the job. Then give a wide range.
Speak about specifics that relate to the position you are applying for. If you do not have specific experience, get as close as you can.
