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.

For a fillet weld between two pieces of 5 mm thick mild steel, the recommended leg length is typically equal to the thickness of the thicker piece being welded, which in this case is 5 mm. However, a common practice is to use a leg length of 6 mm for added strength and to ensure proper penetration. It's important to follow relevant welding standards and guidelines that may apply to your specific application.
What is the difference between blue seam and red seam police in Jamaica?
In Jamaica, the blue seam and red seam police differentiate between two types of officers based on their roles. The blue seam refers to regular police officers engaged in general law enforcement duties, while the red seam typically represents specialized units, such as the Jamaica Constabulary Force's Mobile Reserve or other tactical teams. This distinction helps in identifying the officers' specific functions and areas of expertise within the police force.
What is the maximum safe g-force on a roller coaster?
probably around 3G - to keep it safe for most individuals
Flow rate cannot be converted into pressure units. So, you should give up the idea.
What is crank and slotted quick return mechanism?
A crank and slotted quick return mechanism is a mechanism that has a slotted lever attached to another lever and a wheel. These types of mechanism are frequently found in shaping machines.
How does' the MOD II stirling engine work?
Variable dead-space chambers that decreased in size with the throttle request. More throttle = less dead-space allowed in the engine. Other than that, it operated like any alpha-design stirling engine. See the link below for more information on the exact design.
Where are electromagnetic clutches used and why?
They normal clutch mechanism but driven by electromagnetic solinoid coils. They are used where the motors are to be engaged and disengaged during running, with out stopping the operation.
Can you give me Technical description of an iPod?
It has a body of a regular ipod,its just that it has more feautures of a ipod has
How can you measure temperature using thermopaper?
Paper Thermometer Thermopaper is used to measure the maximum temperature that a surface has reached. From the manufacturer's website, paperthermometer.com, the directions are:
- Affix Thermopaper on a clean surface.
- Heat/run through procedure that is being tested.
- The gray/white temperature sensitive element will turn to black if the surface has reached the rated temperature.
yes the perpendicular component of earths magnetic field passes through the loop even if the car is moving above it or not , but no current is induced in the loop since it is not moving
Why hemispherical head for pressure vessel?
Hemispherical head is the strongest of all heads.Therefore it is used.
After welding SS316 how to release the stress?
You can fasten your fabrication to something that won't flex easily, like an I-beam. When the welding is done wrap the whole thing up in Kao-wool, which is a type of insulating material, and let it cool down SLOWLY. This keeps stresses to a minimum and helps to keep your fabrication from warping. It is very difficult to keep stainless from warping, but it can be minimized. I've been on jobs (refinery, nukes) where the pipe fabrication had heating elements attached to it, brought up to just below the welding temperature, wrapped in Kao-wool, and the temperature decreased in a controlled fashion over a specific period of time ie: 80 degrees per hour. This data was recorded and made part of quality control package.
What will happen to a centrifugal pump bearing if it is too hot?
The diameter of the bearing balls increased and the volume is locked.
Why do magnets stick to stainless revolvers?
This has got to do with the amount of Chrome in the alloy used to make the revolver.
With a lot of chrome in the alloy, the bonds between chrome and iron would not allow for magnetic interaction.
Most stainless steel is magnetic though if one just applies a strong enough magnetic force.

How is the toilet paper dispenser a wheel and axle?
because when you take some paper towels of from it.it goes like a circle and like a wheel too
Is a mechanical engineer involved in theory practice or both?
I believe the professional mechanical engineer is involved more within the theory and design, where the mechanical engineering technologist is more involved in the practice. However, I am not an engineer and this is a personal opinion based on the design of such programs of study.
What is the cut out temp on a steam boiler?
Steam Boilers don't usually cut out on temperature but when they reach a preset pressure.
Which company led the air and gas compressors industry?
Ingersoll-Rand Company has long been one of the top U.S. air-compressor manufacturers. By some estimates it was the largest U.S. producer and the world's second-largest.
What is the function of mainfold block in hydraulic cylinder?
The manifold block directs the hydraulic fluid into or out of the cylinder.
What is the name of a plane other than a helicopter which can take off and land vertically?
Answer: AV-8 Harrier II jet is one. V-22 Osprey is a Tilt-rotor craft that flies in both Helicopter mode and aircraft mode by titling its engines/rotors. It just went operational last year.
Ships have been around since the Phoenicians started their trade empires around the Mediterranean. Probably before.
