How Can Eigenvalues Calculate Resonance Factors?

-“The wavelength is 0.20 s.” This is wrong because wavelength’s unit is meter and it measures the distance between two adjacent locations in the disturbance, not the time one particle takes to finish one vibration.

The trace statistics ʎ trace and the maximum Eigen statistics ʎ max were used and the results are presented in table 3 and 4 below.

After the positions were recorded for frequencies 1,803 Hz, 2,402 Hz, 3,002 Hz, 3,600 Hz, and 4,201 Hz, the wavelength was determined for each. This was done by subtracting the initial position from the final position (position final–position initial=wavelength). Using the calculated wavelength, the speed of sound in air at each frequency was determined by multiplying the wavelength by the frequency (speed of sound=wavelength x frequency). By adding the five speed values and dividing by the number of speeds, the average speed of sound was calculated. Then 344 m/s was used as the accepted

Suspension bridges usually experience torsional forces during very windy conditions where there are high wind speeds, this can create a twisting force causing the deck to rotate resulting in the bridge experiencing shear stress. (Bagga

One of the most influential engineering discoveries in the past century was the ill-fated Tacoma Narrows Bridge. “Galloping Gertie” as she was known to local residents, the massive Washington state suspension bridge shook, rattled and rolled its way into the history books. Legendary in its time, the Tacoma Narrows Bridge held many records and drew tourists from around the world in its short life. However, the famous bridge is not known for its creative engineering or speedy construction, unfortunately the bridge was destined to fail. That failure in turn changed the way every building is constructed today as well as further man’s understanding of physics and the forces of nature. In this paper we

Due to the design complexity of the Glasgow tower, construction could not start until a variety of wind tunnel test were completed. Mean hourly wind speeds along the river basin were used to measure the aerodynamic effects of the tower. Computational fluid dynamics programming was used to test the final design of the tower components. The project management team also did a good job in selecting the contractors from a pool over 70 international companies; the

Although these problems were corrected and the idea of building a skyscraper became a feasible task, there were many conditions that had to be taken into account, that did not need consideration when building a structure less than 40 stories tall. Four story buildings are supported by their own walls; however a new method needed to be created for skyscrapers since the previous building method would not provide enough support. Metal skeletal frames made of columns and beams were then developed to provide the support and strength needed for the skyscrapers. As the buildings grew taller, their structural design was made lighter and stiffer. Also, as the buildings grew taller, wind became an important issue. Normally, the force that acts on the skyscraper pushes directly downward towards the ground that would then counter balance that push. However, when an additional force acts on it, such as wind, the forces would act differently on the skyscraper. With a lateral force acting on the building, the steel columns of the frame on the windy side would stretch apart slightly while the columns on the other side would compress. Therefore, the skeletal frame built had to be made so that the structure would be free to move slightly with the wind and, at the same time, remain sturdy.

My dependent variable how much weight each bridge can endure before the bridge breaks apart. When you add weight tension is created. (tension is a pulling force that occurs at the bottom of a bridge) when tension is applied the connecting points (glue, pieces that snap together, etc.) will unconnect so everything will fall apart and the bridge collapse to the ground.

In Figure 7, the frequency of the basis functions vs. sample that appear in full and sequential sampling are plotted. The correlation of the frequencies is 0.87 and sequential sampling provides a band of uncertainty around the numerical solution while being efficient.

22,050 kHz. Recall each time Matlab is run this is equivalent to a different experiment

In this method, the challenges from that emanated from the previous methods are solved through the development of a quicker way that solves the same problems in a short duration. The goal of the project was to obtain an easier methodology that can help in solving systems of eigen problems. In particular the study aimed at obtaining anything that solve a collection of problems. The new methodology adopted not only maintains the solution requirements but also introduces systematic improvability. Through the new insights added to the new method which distinguishes it from the previous methodologies, the required accuracy coupled with a fewer degree of freedom can be achieved.

Thus, components like a mast or bridge girder can be analysed more comprehensively with compartively with lesser degrees of freedom.

Create a simple model using Matlab, simulating the multi-storey structure which returns all the natural frequencies from the numerical methods in the model.

In spite of their appearance, these massive spans serve no practical function. They are strictly ornamental and do not help support the structure, which was the first object built to withstand the forces of the wind as well as gravity. Only now, more than one hundred years later, can we see the tower in context. It has aged gracefully and no longer stands in contrast to the ornate architecture that has survived in modern Paris. Once the exposition was over, plans were made to destroy the Eiffel Tower. The monument that brought so much displeasure because it represented that which was modern, new, and very un-Parisian, was actually saved by technological advances. Engineers realized that the structure would make a perfect broadcasting tower.
