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.

The bed length of a lathe is the total length of the bed way from where it starts to (close to the headstock) to where it ends.
When a lathe is advertized for sale it would show for example: 200mm x 1000mm or 8" x 40". The 200mm or 8" describes the "swing" of the machine and the 1000mm or 40" describes the workable distance between the chuck and center. This should not be confused with the bed size of a lathe as the bed houses the tail stock and therefore the distance is shortened.
What is the difference between seamless and stainless?
'Seamless' means without a 'seam' (a seam is a join therefore seamless stockings are kitted as a tube rather than being cut out of flat material then joined into a tube by stitching).
'Stainless' means without a 'stain' ( a stain is a discoloration or blemish, thus stainless steel will not rust and and therefore a knife made out of this steel will remain new looking throughout its life while an ordinary knife blade will blacken and rust with age).
A machine vice is a device used to hold a work piece when operating a milling machine or adrill press. The machine vice is adjustable in many different ways, allowing the work piece to be manipulated into any angle or position required. This type of vice is crucial when a certain angle is required to be repeated on several pieces. The machinist can mount the work piece and adjust the vice to the desired angle and position and the machined finish will duplicate the prior pieces exactly.
It should be noted that there are two common spellings of this piece of machinery. In the United Kingdom, when referring to a machine vice, the word is spelled vice. Alternatively, in the United States, machine vise is used.
In some milling operations, the cutting tool remains stationary while the machine vice is used to move the work piece into the cutting tool and complete the machining operation. The precision movement of the machine vice allows the machinist to create pin-point operations by manipulating the vice's controls. In other operations, the machine vice is simply used to position the work piece while it is milled. This typically occurs when machining a work piece that is flat and square.
The English term 'igniter' has a couple of distinct uses:
1: an actual device used for for lighting fires or igniting fuel (as in a gas engine) or setting-off charges (as in firearms or bombs);
2: a particular substance (such as gasoline or paraffin) that is used to ignite or kindle a fire.
To find the mechanical advantage of a simple machine divide output force by input
force. (input force is the force that we exert on a machine, and output force is the force that is exerted by a machine).
Where can you find a breakdown manual for a Browning 12 gauge pump?
To start, I would contact Browning. If it's an old gun and they can't help, check the ads in the back of the American Rifleman, Guns and Ammo, Outdoor Life and similar magazines. There are book dealers who specialize in that sort of thing. Good luck. Browning.com You can download in PDF format all the manuals, old and new.
What type of pump is jockey pump?
A jockey pump is a small pump connected to a fire sprinkler system and is intended to maintain pressure in a fire protection piping system to an artificially high level so that the operation of a single fire sprinkler will cause a pressure drop which will be sensed by the fire pump automatic controller, causing the fire pump to start. The jockey pump is essentially a portion of the fire pump's control system.
What issues arise when cutting a 6 inch schedule 80 x 90 degree elbow to make 2 x 45 degree elbows?
cut a 22 1/2 out of it
How does a machine tell the difference between one dollar and five dollars?
Vending machines have laser scanners that can tell the difference between the bills.
Same, use bi if the gene products will be too big to resolve.
How much do mechanical engineers get paid yearly?
How much does anyone get paid? It varies a great deal depending on experience and the nature of the industry. Also, you need to look at the average hours worked per week and the nature of the job

Is st grade equal to SS 304L with DIN standard?
AISI 304/304L -DIN 1.4301/1.4306-1.4307
so 304 equv. DIN 1.4301
304L equv DIN 1.4306-1.4307
An angle subtended by an arc is double at the center?
an angle subtended by an arc is double at the center
A wedolet is a butt-weld branch connection. It is used to minimize the stress concentration and to provide integral reinforcement.
in refrigeration CoP =Qo/w
= Todelta S/(Tk-To)delta S
= To/Tk-To
Ec = 1/(Tk/To)-1
in heat pump CoP = Qk/W
= Tkdelta S/(Tk-To) delta S
= Tk/Tk-To
Eh = 1/1-(To/Tk)
