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.

I think there are 4 types of load cells they are Pancake Load CellS ,Beam Load CellLoad, ButtonSingle and Point Load Cell.
How deep hydro Abrasive Water jet machining can cut?
That depends on what you are looking to do. The Grand Canyon was essentially cut with this process, after all.
The limits to depth of cut for abrasive waterjet cutting and machining are not so much real limits, but it gets slower and slower the deeper you go / the farther from the nozzle the cut is.
The thicker you go, the slower, and it is an exponential function, so twice as thick is more than twice as slow. The equation for this can be approximately expressed as "Velocity = (1/Thickness^1.15)"
If you are talking about the realm of being practical, then here are some ball-park numbers:
- Steel: Starts to become impractical at about 3" (75mm) thick, depending on the shape. Some people cut up to maybe 12" thick, but rarely is that practical.
- Aluminum: About 1.5 times thicker than steel.
- Titanium: It cuts about the same as aluminum, though people often cut thicker because titanium is so expensive that waiting a long time in order to have the advantage of cutting with a narrow slit, and thus saving material, can be a huge money saver even though the cutting may be slow.
- Stone: Most stone cut with this technology is done to thicknesses of maybe up to 3", though it is quite reasonable to cut even thicker if you are willing to wait. The primary application here is granite and marble flooring and countertops.
It really is a question of "how long are you willing to wait / how much money are you willing to spend in consumables and machine time".
For mining applications people can cut thicker by cutting in, removing rock, cutting deeper, removing rock, etc. There are a lot of mining applications that I am not very familiar with that cut quite thick.
Hope this helps.
How do differential hydraulic cylinders work?
A differential cylinder has a large piston that requires a greater amount of oil to displace the cylinder, thus allowing greater uniformity of force than a typical single-acting cylinder.
Is cathodic protection required for stainless steel pipes in underground porsion?
Certain grades of SS are prone to corrosion when buried or exposed to contaminants that destroy the SS's passivating surface layer.
When Ferdinand Verbiest invented first car?
During the 1670s, Verbiest designed what some claim to be the first ever self-propelled vehicle. It is believed to be the world's first automobile, in spite of its small size and the lack of evidence that it was actually built.
What are the machines used in a construction site?
Many different machines may be used in construction. Two that you always see are a large compressor and a large generator to run all the tools.
How do you find if drill bit is worn or not?
Try drilling some metal with it. If it doesn't start cutting in immediately, it's worn. They can be sharpened much cheaper than buying a new one. - -Back when I went to school this was basic learning in shop classes.
-Of course, they forgot to tell me whether it was a 'class 2 ' lever or not, so maybe I missed out on 'real' learning. -LOL
How do you protect construction steel bars from corrosion?
the concrete cover protects the steel bars from corrosion and environments or members more prone to corrosion or chemical attack such as in footings the cover thickness is increased
in members where the concrete will come to direct contact with the soil a blinding layer of about 10cm is used to separate the reinforced concrete from the soil.
also coating steel bars in corrosion resisting chemicals is used for more protection
What is the difference between gutation and respiration?
Respiration is k gaseous exchanging process while Gutation is the formation of water droplets on pores at the edges of a leaf..
What is the difference between a triplex mud pump and a duplex mud pump?
A positive-displacement reciprocating pump that is configured with three plungers. Triplex pumps are the most common configuration of pump Pumps used in well service activities generally are capable of handling a wide range of fluid types, including corrosive fluids, abrasive fluids and slurry's containing relatively large particulates.
A type of fluid pump, commonly used on work-over rigs, that has two plungers or pistons. As a positive-reciprocating pump, the fluid flow rate is typically calculated from the number of Stroke/Min that the pump makes and the displacement volume per stroke. Such a level of accuracy usually is sufficient for general work-over purposes.
What type of alloy metals are made of bismuth alloy?
Alloys are obtained by melting the base metal with the alloying components.
What is the effect or reheater in the gas turbine?
1.Turbine output is increased for same compressor work.
2.As more heat is supplied,thermal efficiency decreases.
Which is more sensitive. temperature scale or celsius scale?
Question is ambiguos, because celsius is a unit meaure of temperature.
What is the difference between a spline shaft and axle shaft?
A spline shaft is a cylindrical shaft with grooves or splines cut into its surface, allowing for a secure connection with other components, typically enabling torque transfer between parts. In contrast, an axle shaft is a type of shaft specifically designed to transmit power from the vehicle's differential to its wheels, allowing for rotation and movement. While both can feature splines for connection, the primary function of an axle shaft is related to vehicle propulsion, whereas spline shafts serve broader applications across various machinery and mechanical systems.
