The aim of this investigation was to find the stress intensity that was present when a finite analysis of a cracked plate was conducted. The results that were gained from using the software, ANSYS, were verified with theoretical hand calculations. The stress intensity (KI) was found to be 0.42 Pam1/2 using the finite element analysis…

In order to test two standard tensile specimens, one metal (aluminum 2011-23) and one non-metal (polypropylene), we used a computer-controlled universal testing machine (UTM) that operates by the rotation of two power»screws. The UMT moves a cross member attached to the end of the specimen away from the other end. Using MATLAB R2014a, we determined…

Discussion The lab was completed as instructed and the results obtained were used to plot a graph of pressure against strain for each of the three grids. The line produced by the ratio plotted was linear in nature which yields that pressure is proportional to strain. This was gave a direct relation to Hooke’s law…

The study of the nature of light is an important research area in modern physics. Many, including the theoretical physicist Albert Einstein, have contributed to theories involving light. Of these, the wave-particle duality is arguably the most strange and noteworthy concept in the field. Throughout history, some physicists have argued that light behaves as a…

Quantum Mechanics, a branch of mathematical physics, explores the emission and absorption of energy by matter, as well as the motion of material particles. Its focus on energy and matter existing in discrete amounts makes it particularly applicable to Elementary Particles and their interactions. In contrast, classical physics treats energy as a continuous phenomenon and…

Abstraction Fourier-transform infrared spectrometry has been really utile in assisting scientists analyzing molecules of HCl and DCl. Because heavy hydrogen has a greater mass than H. the IR set shown for HCl is at a higher wavelength than DCl. The soaking up of visible radiation in DCl was at lower frequence 1700-2200 cm-1 because D…

For John Wheeler. specifying the term “quantum” in his essay “How Come the Quantum” ( Best 41-43 ) seems the least of his concerns. It’s a “thing. ” he says. “a package of energy. an indivisible unit that can be sliced no more” as Max Planck’s observations 100 old ages ago indicate ( 41 )…

This article, while not wholly focused on the Higgs Boson particle in itself, discusses the possible consequences or effects that this discovery might have on other subjects. As the research continues to progress, the existence of this controversial particle is further reinforced, as the pot continues to be stirred. Like a drop of water falling…

“As we shall see, it is generally believed that the phenomenon of superfluidity is directly connected with the fact that the atoms of helium-4 obey Bose statistics, and that the lambda-transition is due to the onset of the peculiar phenomenon called Bose condensation” (Leggett, 1989). This is the phenomenon wherein the bosons (a type of…
