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.

Describe what your day to day tasks and activities might be as an Analyst on a project?
A project analyst analyzes, reviews and documents the requirements of a project throughout its term. They advise a whole team of people and help guide the project through to completion.
Why is stainless steel called stainless steel if it can be stained?
Because it stains less easier than regular steel. It's not 'stain proof', it's just more resistant to staining and rusting. Think of it as stain less.
What material stype is it astm a-216?
ASTM a-216 is cast material , it is formed by low carbon steel content. A 216 can be given pressure max 2000 psi/137 bar
What is purpose of using Intermediate and Low pressure turbines in a thermal power station?
To obtain as much mechanical energy from the steam produced in the plant's steam raising units as possible, it is expanded through increasing sized turbine wheels, eventually expanding into a vacuum in the turbine condenser before condensing and returning to the steam cycle.
What is the cubical coefficient of thermal expansion for metals?
Since most metals are isotropic, the cubical coefficient of expansion is three times the linear coefficient of expansion.
The linear coefficient of expansion is obtained from measurement and tables for the specific material which are readily available.
How can I purchase M6 or M8 mounting bolts?
These are standard metric screw/bolt sizes. You should be able to find them at a local Hardware Store. Such hardware is also available online.
What type of welding is used in fence manufacturing?
Resistance welding plants are used in fence manufacturing.
What are the types of tensile structures?
Tensile Structures various type
- Tensile fabric membrance structures
- Mesh Fabric membrane structures
- Modular Tensile Fabric Structures .....
Which country is known as the Saw Mill of Europe?
Sweden is called as the saw mill of Europe.World-wide, Sweden is the third largest exporter of sawn timber. In Europe, the Swedish saw milling industry holds a prominent position, as the second-largest producer and the largest exporter of
sawn softwood.
What was the mechanical reaper?
A machine designed originally to be pulled by horses (later a tractor) that automatically harvested, winnowed, and collected grains like wheat, barley, and rye. It was much faster than doing it manually and allowed dramatic growth in size of farms as well as reduction in use of crop rotation and increase in use of fertilizer.
Can a convicted felon become a mechanical engineer?
hell yea. don't listen to negative people. u can do it . get your bachelor in engineering and let at least 5 to 7 years pass since the incident. when interviewed, explain what happened and that u changed and want a good life. engineers can work independently
You heat the metal and the metal turns red. It is not as hard and while it is hard you use the hammer and shape it!<( *)3 <---a chicken
What is the application of keys in mechanical engineering?
Keys are used while joining two shafts using couplings. When the shaft rotates at speeds greater than what it is designed for, The key purposefully undergoes failure and thus prevents damage to both the shaft and the coupling.
The steering wheel, knobs to turn on electric gadgets such as wipers and radio, the pedals for the gas and brake, the levers that pull your seat forward and backward.
What is Surge in centrifugal compressor?
Surge is a flow instability that results in a global collapse of flow through the compressor.
Compressors do not continue to operate or flow once surge has occurred. Surge should be avoided.
Surge is not the rough operation, vibration, pulsation, or noise that develops at low flow conditions.
Surging is a momentary reversal of flow.When the pressure in the centrifugal comp. increases,the mass flow rate decreases.There is a limit up to which the pressure can be increased,then after the flow becomes instable and momentary reversal of flow take place,vibrations are produced and mechanical damage occurs.
What are the risks associated with your working environment?
Some of the risks include electrocution, burn hazards, falling hazards (example:you are putting in conduit in the ceiling of a tall building), some heavy lifting/pulling, etc.
The IN5408 diode is an ordinary silicon diode. It has a 3 amp forward current rating, and a 1000 volt peak reverse voltage rating.
Definition of terminology in mechanical field?
Terminology (also called Nomenclature)is just a simple word, its not much specified in fields, its a general term for all fields. Terminology refers some particular thing to define its system or its working. See related link below for more information.
Yes.It is very rare compared to the elderly population.If it occurs in a young person it is usually associated with infection,vascular malformations of brain,diseases of heart or blood coagulation unlike elderly where it is realted to atherosclerosis,hypertension,diabetes etc.
What are the advantages of lean manufacturing?
Primarily, lower manufacturing costs due to the elimination of wastes. Also, lean tecniques encourage production to be better matched to demand, which can result in improved response to customers. Overproduction is one of the wastes reduced or eliminated (and really the worst of them), and improved customer response and no overproduction can result in more control over pricing and margin. So, costs are reduced and revenues may be increased in a successful lean enterprise.
