In semi and fully automatic guns it is a simple mechanical process. The magazine holding the rounds has a spring on the bottom of it. As the slide retreats back from the breech the empty shell is "sprung" out, the slide then closes back over the breech at the same time a new round is sprung up into place.
1. Stress: when a structured weakens because of too many forces.
How do you set instrument zero readings?
There is usually some sort of adjustment device so that you can set the instrument to read zero for zero input. Otherwise you need to note the amount of zero error and remember to subtract it from your readings when you do an experiment. When you set the zero, you are trying to get the job you are doing as accurate as possible. It is important when carrying out the testing and inspection of the equipment that the test gear is reading zero. This means that any reading taken with the equipment will be true reading of the circuit and not include the resistance readings of the meter being used for example.
The process is known as nulling the test equipment, this can be carried out on some pieces of test equipment with the use of an auto null button on the machine..

redundant forces are the extra forces in a structure whose removal from a structure makes it statically determinate.for ex:in a structure of indeterminancy =2 ,2 forces can be removed
What helps make a rocket take off?
Basically "thrust", which is the difference between the air pressure in at least 2 different places who are connected to each other.
What is hydrostatic pressure used for drilling oil wells?
In Drilling terminology, hydrostatic pressure is "The pressure exerted on a column of fluid at rest". This said, an oil well is just a column of fluid. Hydrostatic pressure is used to control the formation pressure in a well in order to prevent a "kick" (an influx of fluid into the well bore) or a blow-out (an uncontrolled influx of fluid into the well bore). Hydrostatic Pressure is calculated by a simple calculation = depth in meters x weight of drilling fluid in kg/m3 x gravity constant of 0.00981. IE. drilling at a depth of 3459m with drilling fluid that weighs 1120 kg/m3 would give you a Hydrostatic pressure of 38005 kpa. This is the amount of pressure that is being exerted on the formation at 3459m
Calibrated torque wrench method?
the most accurate calibrated torque wrench was using the TWT torque wrench tester products that produce by Stahlwille. Its also called transducer.
What is the year the ping putter 1A 85068 was made?
1959 is the answer. I quote from the Ping.com WEB-Site (Karsten Solheim invents the PING putter in his Redwood City, California garage. he names his putter "PING" because of the sound it makes upon contact with a golf ball. Two years later, he moves his family to Phoenix and continues his quest to improve golf club design.) Putters from PING don't "Ping" anymore. There are still 1A putters for sale. The new ones are not made of copper as was the original.
Can two pulses traveling in opposite directions on the same string reflect off each other?
Only if the string is in a loop or there is something at the opposite ends of the string to provide a reflection or echo. If there is an echo then slightly weaker pulses will reflect off of each other near the point of origin.
What is the name of the radio engineer that is a principle inventor of T.V.?
What is the name of the radio engineer that is a principle inventor of T.V.?"
Does the weight of a gallon of water increase when an object is floating in it?
Yes. The floating object is an addition to the mass system, even though it cannot displace its entire volume in the water.
What do six sigma process generally consist of?
The Six Sigma process consists of statistical methods to analyze the processes systemically. Methods are used to reduce process variation and to drive production to almost perfect.
Why was the steam train invented?
To get from point A to point B faster and safer
n the 1820s the port of Baltimore was in danger. The threat came from the newly opened Erie Canal (see "Traveling the Erie Canal, 1836") and the proposed construction of the Chesapeake and Ohio Canal that would parallel the Potomac River from Washington, DC to Cumberland, MD. These new water routes promised to provide a commercial gateway to the West that would bypass Baltimore's thriving harbor and potentially hurl the city into an economic abyss. Something had to be done.
A Modern Reconstruction of
the Tom Thumb
The local entrepreneurs looked across the Atlantic to England and found an answer in the newly developed railroad. In 1828, the Maryland syndicate, led by Charles Carroll - a signer of the Declaration of Independence - broke ground for the Baltimore and Ohio Railroad. The railroad's objective was to connect Baltimore with the Ohio River and the West. Initially, the railroad's power was to be provided by horses. However, it soon became obvious that animal muscle was no match for the long distances and mountainous terrain that would have to be traveled. The solution lay with the steam engine.
By 1830, the B&O Railroad had extended its track from Baltimore to the village of Ellicott's Mills thirteen miles to the west. The railroad was also ready to test its first steam engine - an American-made locomotive engineered by Peter Cooper of New York.
It was a bright summer's day and full of promise. Syndicate members and friends piled into an open car pulled by a diminutive steam locomotive appropriately named the "Tom Thumb" with its inventor at the controls. Passengers thrilled at the heart-pumping sensation of traveling at the then un-heard speed of 18 mph. The outbound journey took less than an hour. On the return trip, an impromptu race with a horse-drawn car developed. The locomotive came out the loser. It was an inauspicious beginning. However, within a few years the railroad would become the dominate form of long-distance transportation and relegate the canals to the dustbin of commercial history.
Who invented the first mechanical cooling system?
The first mechanical cooling system was invented by Dr. John Gorrie. -Qwasas
What does the S mean on the gear shift in a 1988 Acura Legend?
"S" stands for sport. In this setting, the transmission has higher thresholds for upshifts and downshifts a lot faster. There are 2 sport settings, S3, which only goes up to 3rd gear and it is useful for driving on hilly terain, and S4 which is like drive, but with higher thresholds.
What is concurrent system design?
It is a systematic approach to integrated product design or product that emphasizes the response to the customer expectations and the combination of uniqueness and engineering. Concurrent Design mainly focuses mainly on the early phases of the project or product. Its central concept is the use of collocated sessions during which the team shares and discusses all design aspects in a structured way, usually in the presence of the customer.
power = speed x strength So to increase your power you must: 1) increase the speed at which you can perform the movement 2) or increase the amount of weight you can perform the movement with AND the speed at which you can perform the movement Generally speaking one will see improvements with any improvment in speed OR strength. Once you reach professional level competition with highly trained atheles it becomes a little more complex than simply increasing one of these variables.
