Its in order to reduce the internal stress of the working
substance.

For eg., If Water Vapour Dry is the working substance in
the reactor or boiler and if the ends are square, at the
corners there are possiblities of pressure shoot up and
also possiblity of more pressure concentration at those
points. in order to avoid that, Spherical/Hemispherical
Vessels are used.

One more place where Spherical vessels are used for storage
is LPG Storage Containers

Answer / karthick

i think sharp corners enhance stress concentration.if the
pressure of the fluid is raised against these corners crack
propagtes.so rectangle or square or triangular shape is
uneconomical.so it is made up of cylindrical shape

what are the parameters are selected while manufacturing a single cylinder block?what are the different kind of test is conducted on it so that it can withstand with all those condition which required to run the engine efficiently.which force is act when piston slide inside the cylinder.

Hello there, Im a Mechanical Engineer. I passed out in 2010 and have worked for 6 months in the Middle East as a Trainee Engineer. Im now in India and due to appear for an Interview for a firm in the Middle East. The post is of an Automobile Engineer. Im kinda nervous as to what to prepare for the interview. The training which I got was in different areas ranging from technical to managerial aspects. What I mean to say is that that was more of a crash training, where I couldn't stick to one section alone. The interview which Im attending is more of a technical one. What I would like to know, how and what I should be preparing? I have two weeks for the preparation. Should I go through the normal automobile aspects or everything in random. PS: I have excellent communication skills, the one area in which I'm very confident.
