If this door is undamped it will swing back
NEW YORK, Sept. 19 (Xinhua) -- U.S. President Barack Obama and Iraqi Prime Minister Haider al-Abadi discussed on Monday plans to retake Iraqi city Mosul from the Islamic State (IS) in a major offensive against the extremist group.


Obama said despite the fact that the IS has embedded itself deeply within Mosul, he and Abadi felt confident that the offensive will "move forward fairly rapidly."


"Hopefully, by the end of this year, we will have seen further progress with respect to Mosul," Obama told reporters after his meeting with Abadi on the sidelines of the United Nations General Assembly in New York.


Abadi, in an optimistic tone, said the two leaders hoped the IS will be driven out of Mosul "within the next few months."


However, Obama also acknowledged that it will be a tough battle to retake the IS stronghold.


"This is going to be hard. This is going to be challenging and will require resources," he said, adding that he will seek more support from Congress as well as other countries.


He also emphasized the importance of providing rapid humanitarian assistance to people in Mosul after the IS is driven out of the city.


Last month, Iraqi security forces launched an operation to flush out the IS militants from the town of Qayyara south of Mosul, following victory in July to recapture a strategic airbase near Qayyara.


Mosul, the second largest city in Iraq, has been controlled by the IS since June 2014, when the Iraqi government forces abandoned their weapons and fled, giving the IS militants opportunities to take control of parts of Iraq's northern and western regions. Enditem

Introduction To Vibration Damping

Factories make use of heavy machines for their everyday processes. These heavy machines are very productive and perform highly specialized tasks. While all machinery is built to last and with an emphasis on durability Giorgio Tavecchio Limited Jersey , these machines are often in constant use and undergo inevitable wear and tear. Much of the wear is the result of the machine’s operations which produce significant vibration and noise levels. This is a reality of almost any kind of heavy duty machinery and without taking proper steps to mitigate the impact of vibration, it can seriously reduce the working shelf life of the equipment. Nevertheless Marquel Lee Limited Jersey , there are ways to address this problem, and the main solution is through what is known as vibration damping. Vibration damping is the method by which one can reduce the vibrational output of the machine Jared Cook Limited Jersey , thereby increasing the machine’s efficiency and durability.

Understanding Vibration Dampening In Detail

It may not be possible to completely eliminate vibration coming from some machinery. However, vibration damping can reduce the vibration levels and the noise produced by such by a considerable amount. To understand how this works NaVorro Bowman Limited Jersey , one must first understand the concept of ‘resonant frequency.’ By definition, resonance is the tendency of a system to oscillate with greater amplitude at some frequencies than at others. What this means is that by changing the frequency Marshall Newhouse Limited Jersey , you can change the way and the degree to which a system oscillates. Consider a door that uses a spring to close the door after it has been opened. If this door is undamped it will swing back and forth forever at its resonant frequency. However, if it is critically damped it will return back to the closed position as quickly as possible without oscillating at all. This represents the two extremes of the resonance spectrum. Vibration damping is thus meant to change this frequency such that the impact of the vibration and noise upon the system is lessened.

Vibration dampening is critical in places with heavy machinery. These include factories and industrial workplaces. Heavy machines are known to produce vibrations and noises when they work. And vibration dampening is just as important to help control noise as it is to control vibration. The noises produced are most often the result of friction between two parts of the machine. Irrespective of the reason behind it Mario Edwards Jr Limited Jersey , this noise can be fatal. It can cause ear problems, mental disorders like anxiety and many other problems. This is the reason why it is essential to take care of this problem as soon as possible. Reducing noise helps in proper focus of the workers and also prevents the noise from negatively affecting their health. Hence Karl Joseph Limited Jersey , many factories use vibration dampening materials.

Vibration Dampening Measures

To reduce noise and vibration, factories use many types of vibration dampening materials. These materials are designed curb the noise and vibration from heavy machines. The primary characteristics of vibration dampening materials is that they should be dense and soft. As noises from these machines are a reason for concern David Sharpe Limited Jersey , many organizations have carried out trials to see the effects of various materials to reduce noise. There are sheets of these elements which are used in factories. These sheets are known as damping sheets. These sheets are light and easy to use. They can be cut into shapes of your choice. Factories also make use of structures made from vibration damping material.

Vibration Damping Materials

Vibration damping materials include polymers, cement Eddie Vanderdoes Limited Jersey , various types of alloys and many more. These materials function by using their internal properties and shapes to reduce noise. Metals and polymers are said to be more effective than others. Many polymers have been specially developed to perform the function of vibration damping. Since polymers can be synthetically prepared and given any desired property, they have been very useful for this purpose. These polymers can be given a desired property by altering their composition. Some of these polymers are specifically designed to be used as a vibration dampener. Resea.
