single, flexible strand or rod of metal which is typically cylindrically-shaped. The core applications of wire, both single- or multi-stranded wire, are to withstand or carry mechanical loads in construction sector, whereas in electrical and electronic field are used to transmit electricity and telecommunications signals. For examples, from view of construction, wires are either braided or fixated together to form a bundle of strands, namely multi-stranded wire or conventionally known as cable,…
of a fluid is expressed in the form of conservation laws of mass, momentum and energy.The magnetohydrodynamic phenomena are a consequence of the mutual interaction of the fluid flow and the magnetic field. As is well known, a conductor crossing magnetic field lines gives rise to an induced electric field, which causes an electric current in the conducting fluid. The following are the Maxwell,s equations ∇⋅D = ρcf ∇⋅B = 0 ∇×E = −∂B ∂t…
Fig: Schematic representation of LHC and it's detectors The primary objective of LHC is to answer the following questions: 1. Why some particles are heavier than others? If the Higgs mechanism is valid? 2. If the super-symmetry theory is valid? If yes then if super-symmetric particles exist? 3. If the concept of dark matter and dark energy correct? 4. Why our universe is made up of matter only? 5. What was the state of matter in the early universe? 6. What will be the properties…
What chracterizes the axial flow turbine is its rotation axis. It could be placed vertically or horizontally to water surface. In this latter type the axis is parallel positioned to the incoming water stream. Also the generator can be submerged under water or non-submerged. This turbine is usually used as tidal energy converter. For small river use, the axis could be an angle inclined to the water stream. See figure \ref{Hydro_HorizontalAxis}. Hydrokinetic converters with a vertical axis…

CHAPTER II. REVIEW OF THE RELATED LITERATURE A. Temporary Magnet Temporary magnets are those that essentially demonstration like permanent magnets when they are inside a strong magnetic field (Jezek, 2015). They are not like permanent magnets when it's not around in a magnetic field because it loses its own magnetism. Temporary magnets cannot remain magnetized on their own (Boyer 2017). Paperclips, press nails, and other comparative things are cases of temporary magnets. Temporary magnets are…
Investigation Hooke’s Law AIM: To investigate how a spring behaves when a force of load stretches it. To figure out the relationship between the loads added to spring and the extension of spring. HYPOTHESIS: I think that as the load added to spring increases, the extension of the spring will increase. The relationship between them will be directly proportional. The formula of these two variables might be F=kx. F stands for the load added to spring, k is spring constant and x stands for…
stability. Starting in 1975 Pol Pot and the Khmer Rouge army took over Cambodia and started a communist country, while killing 25 percent of Cambodia's population(Pol). Through raising tensions between local countries and Cambodia, the Cambodian Killing Fields were considered to be one of the worst genocides in history that has lasting effects on Cambodia today. Background In 1969, Pol Pot had become the leader of the communist party in Cambodia. He eventually fled into the jungle where he hid…
