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.

Explain Heat Treatment process and its purposes?
Heat treatment process hardens the metal, after tempering In fact heat treatment is very similar to cooking!! Why you cook? to make sth you want! to make sth better.more delicious and .. .
you are doing this process to make the thing you want.for example you want Fe in perlite with special hardness and other mechanical features.so you do heat treatment in a way you want and in pattern that you make.very simple but you must expert!
Filler what can you use for brazing holes in sheet metal?
If the hole is very small the material you are brazing with should fill it. A small piece sheet metal can be brazed in place to cover larger holes.
What type of welding wire is used when welding panel steel?
For steel, flux core or hard wire with Argon/CO2 is used with the GMAW process.
conclusion reaction and moment for propped cantilever beam
Once the water temperature reach -4°,it does not freeze anymore,
Explain briefly about LVDT with working and neat diagram?
First off, LVDT stands for linear variable differential transformer. The principle of the LVDT is that the physical energy is converted into electrical signals.
Which material has the highest value of poisson's ratio?
For isotropic materials, Rubber - very close to 0.5
Some of the simplest machines are?
Ramps (which are also known as wedges), levers, and pulleys are simple machines.
The answer you are looking for is Tools.
Whether water is good fuel or not?
Water is an excellent fuel for internal combustion engine, But, It takes A LOT! of energy to make it to the form to burn
How to refill engine hoist hydraulic cylinder?
Most hydraulic ram cylinders should have a refill plug about half way up the barrel.
1) Position the cylinder vertically, and collapse the ram all the way down.
2) With the plug pulled out, fill the cylinder with hydraulic jack oil until it drips out the plug hole.
3) All done. Place the plug back in and test the functionality.
What was the first helicopter flight?
The first real helicopter flight was made by Hanna Reitsch in a Focke-Achgelis near Berlin around 1937. Consistent and accurate Allied bombing missions destroyed this helicopters production lines so it never got into real development.
What is t he value of a Martin cast iron skillet?
what is the value of a martin cast iron skillet size 8 and 3'' deep
What is Id versus od size in copper fittings?
id means inside diameter, od means outside diameter, copper pipe and tubing is measured by the od, therefore the od the pipe or tubing will be the same as the id of the fitting
How do you stop leaking brake fluid?
Find the source of the leak. Most likely areas are a brake line at the wheels, or the master cylinder at the upper part of the firewall in the engine compartment.
Where do you get final year project on mechanical engineering?
If you are looking for real time engineering models for final semster mechanical engineering projects then, try in SELECT AUTOMATION company.
What does the term lack of penetration mean in welding?
Incomplete penetration (IP) or lack of penetration (LOP)occurs when the weld metal fails to penetrate the joint. It is one of the most objectionable weld discontinuities. Lack of penetration allows a natural stress riser from which a crack may propagate. The appearance on a radiograph is a dark area with well-defined, straight edges that follows the land or root face down the center of the weldment.

What are the spare parts of centrifugal pump?
It depends on the specific pump. For most: the impeller, the wear ring & mechanical seal. In a pump with a packed stuffing box, the packing. In some pumps, the shaft coupling.
What is closed loop hydraulic systems?
It means that the pressurising medium does not leave the system and it is recirculated with make-up or top-up quantity as and when required. This makes it a sealed system to work with.
