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.

What size welding rod do I need for quarter inch metal?
depends but i would use a 3-32 rod preferably a 7018 hope that helps
The most common problems are burn-through, atmospheric contamination, and inadequate penetration. Burn-through (as it's name suggests) is when the metals become too hot and create holes or gaps in the weld joint. Burn-through is most often caused by excessive power through the arc. Atmospheric contamination (most commonly oxidization) occurs when there is not enough shielding from the air to protect the weld and atmospheric gases bond to the metal and weaken the weld. Inadequate penetration is caused by insufficient power in the arc resulting in a temperature too cool to effectively join the metal together.
Minimum CGPA for any core company these days is 8.5...so start working harder boys..
No, a diesel is a compression firing engine and a petrol is a spark firing engine. Diesel fuel will not burn in a petrol engine with spark plugs.
What is electrode function in mold design?
An electrode is used by the EDM (electro discharge machine) in actually fabricating the injection mold. An EDM uses either carbon (like pencil lead) or other material to burn the part shape into the mold. It's not part of the mold per se but used to make it.
What is the difference between air handling unit and the fan coil unit?
AHU v/s FCU
AHU and FCU are both included in the HVAC system. The latter is an acronym that describes multiple systems of heating, ventilating and air conditioning. AHU, completely known as air handling unit is different from FCU or the fan coil unit.
AHUs are usually connected to a central HVAC system whereas an FCU can function or be installed itself. Because of this, it is often the AHU that is used to ventilate an entire building whereas FCUs are used in smaller and often local spaces only. It is no surprise that AHU is the bigger HVAC system not to mention, the FCU is also regarded as the smaller version of the AHU. In this regard, the smaller FCUs can be called terminal units.
Because of the magnitude of the AHU system, it usually makes use of the air from the outside environment. Thus, it treats outside air and brings it inside the vicinity with the use of special ducts while an FCU system on the contrary just circulates the inside air. The latter usually does not have any duct system that’s why it is obviously smaller in size as previously mentioned. It is only composed of a simple coil and fan.
Ordinarily, AHUs have certain features that are not present in the FCU type. AHUs have several sections for reheating and even humidifying. FCUs don’t have sections such as these. Perhaps the only advantage that the FCU has over the AHU is that generally, FCUs can also handle water while the AHUs basically handle air.
Moreover, AHUs can have several fans or blowers installed in its system. Traditionally, the AHU’s blowers are placed at the point where the ducts originate or at the terminal end of the air handler unit. FCUs have a different approach to blowers. Because of its small size, their fans are usually placed within the same space as the unit itself. The result is a minor uncomfortable noise that can be heard within the vicinity. This could be regarded as the single most advantageous flaw of the FCU system.
Summary:
1. AHU is generally a bigger system than FCU.
2. AHU is more complex than the FCU and that AHU are often used in bigger establishments or spaces.
3. The AHU system usually channels air through ducts whereas the FCU don’t have any ductworks.
4. AHU system treats outside air while FCUs basically recycle or re-circulates the air.
5. AHU has sections for reheating and humidifying whereas the FCU does not have any.
6. FCU is often observed to be noisier than the AHU.
How pneumatic or hydraulic systems are used in a pneumatic sand or paint blaster?
Air pressure is used as ejector for the sand blasting.
How can you 'upgrade' from a mechanical engineering degree to a mechatronics degree?
You have to go back and study mechatronics for that.
Does a fridge use pneumatics or hydralics?
it compresses and expands gas so i would say pneumatics but not in the normal sense

Involves the transfer of carbon from one reservoir to another?
i have the same work sheet as you haha!
carbon cycle
Yes, bullet trains have wheels. They run on rails, just as conventional railroad locomotives and cars do. The trains that operate by magnetic levitation, the so-called MagLev trains, do not have wheels as they ride on a magnetic cushion.
radio works 25 watts but if it is valve radio then it works like this listen... turn the volume high enough and quickly do the tone then just tap the off button and turn it on then everything will be installed in it and press play or some others thats the hacked way guys thanks.
What does a standard grain drill do?
plants crops that can live without having to fight light and can be spaced closer or further away from each other e.g barley wheat. unlike a pnumatic precision drill that plants crops like maize and rape seed oil and they are evenly spaced in the ground.
