Mechanical Engineering
Mechanical Engineering is a branch of engineering that encompasses the generation and application of heat and mechanical power and the design, production, and use of machines and tools. Mechanical engineering involves application of the principles of dynamics, control, thermodynamics and heat transfer, fluid mechanics, strength of materials, materials science, electronics, and mathematics.

A valve in the Plumbing sense is a mechanical device to open or close the water flow. It can be a screw operation called a 'Gate Valve' or a simple 1/4 turn handle called a 'Ball Valve' . These are more modern and efficient.

What is the effect on vessels on gm during the filling of a double bottom tank?
The ship cannot roll suddenly over the other side as there is more water in the low side than in the high side. If sufficient weight of water is loaded to bring G (Center of gravity) on the center line below M( (Meta center)
Have you ever done this type of job before in asked in an interview?
Answer
If you have done that type of job before tell the Interviewer you have done it and if you left because of the job, tell them why.

What type of wood is used in making machinery packing boxes?
What ever wood works! In most cases they will use the least expensive wood available that will make the appropriate strength boxes.
A strain gage rosette is, by definition, an arrangement of two or more closely
positioned gage grids, separately oriented to measure the normal strains along
different directions in the underlying surface of the test part. Rosettes are designed
to perform a very practical and important function in experimental stress analysis.
It can be shown that for the not-uncommon case of the general biaxial stress state,
with the principal directions unknown, three independent strain measurements (in
different directions) are required to determine the principal strains and stresses.
And even when the principal directions are known in advance, two independent
strain measurements are needed to obtain the principal strains and stresses.

What is the difference between a steam room and a caldarium?
A steam room is a room heated to around 100 F (40 C) with steam. The room is usually constructed to be nearly air tight, and it operates at about 100% humidity.
A caldarium is the hottest room in the traditional Roman bath house. It was heated by allowing hot gasses to travel beneath the floor and through special channels in the walls. Many times the caldarium would also have a tub of heated water inside of it. The caldarium does not necessarily have a high humidity, and may have a higher temperature than a steam room could because of the lower humidity.
You can see a reconstruction of a caldarium by following the link below.

How much weight can a square of concrete 1 meter on a side and 20 cm thick hold?
There are too many variables that are not quantified in the question to answer this. What kind of concrete? (There are different kinds.) Is the concrete reinforced? How is the square of concrete supported? What is the nature of the load and how is it distributed on the slab? We could go on.
How can the mechanical advantage of a pulley system be determined without using any equations?
by seeing how many ropes the pulley has... that is close to the mechannical advantage...or it is it! its a cool trick once you learn it! My science teacher just had us do a project on this!
What is the use of rubber gasket in door?
On a car, it isolates the air, dust, noise, and moisture outside the vehicle from the passenger compartment.
What is the wall thickness of 500mm pipe?
the wall thickness of sch 40 - 500mm dia pipe is 15mm or 16mm.
How do you troubleshoot a offset printing machine?
I purchased a second hand 2 color offset machine. The problem with the machine is though the condition of all the rollers is good there is an improper transfer of ink.
what is the reason for improper transfer of ink from ductor roller to the first inking roller of the ink train?
dear, first you check the impression setting between duct roller and first feed roller through 1 mm. thick film srtip.
now the question is how you will do this?
this setting is depend on type of the machine e.g. orient and manugraph. the general procedure is to set the impression that you adjust the cam or bolt both side of first inking roller.
second is check the first impression roller condition.
