5. Proposed Research Questions and Tasks Four proposed research tasks will direct to fabrication conditions (Task 1), fabrication thermal analysis (Task 2), fabricated parts performance (Task 3), microstructure control methodology (Task 4), respectively. These tasks are designed to answer the questions and solve the problems in the results of preliminary experiments and observations from reported investigations. 5.1. Task 1. Investigating feasible formation conditions and effects of laser power…

an outside force,” this is applicable to when the gymnast is running toward the vault, as well as, when the gymnast is in the air. Gymnasts use their own force to propel themselves around the bar when performing the uneven bars event and will remain in motion unless acted upon by an outside force, and, in this case, the outside force would be gravity pulling the gymnast downward. Newton’s second law of motion states, “Mass and acceleration are directly proportional in regards to force,” or, “F =…

the difference between motion and forces? Are there different types of motions and forces? What is gravity? What is Newtons law? Does friction have to do with motion or force? Does Newton's law apply to everything that is moving? How is movement and forces apply to the world itself? Do natural disasters involve motion and forces? Does energy have to do with motion and forces? How many types of forces are there? How does the earth create forces? Is an earthquake involve…

Imagine that you are in a world where you can control everything. Flying, apparition, transforming into any form, deciding what happen next, massacre or resurrecting, all these things can be done simply by idiodynamics . Is it a world far from reality? In fact, some people could spend nearly one third of a day in such a world which is called lucid dreams. In a lucid dream, dreamers are aware that they are dreaming and then, if they are skilled enough, control the dream. Lucid dream is a vital…

2.9 Material Properties 2.9.1 Hardness Test Hardness is defined as a measure of a material’s resistance to contained plastic deformation (e.g., a small dent or scratch). Hardness testing comprises a small indenter being enforced into the surface of the material being confirmed under organized circumstances of load and rate of application. The depth or size of the resulting indentation is measured, which in turn is linked to a hardness number; weaker the material, indentation will be the…

the period T, is given by: Ѡ =2πf = 2π/T … Equation [2] The expression for the period in terms of k and m is obtained by combining the two equations as shown in Equation [3]: T = 2π √(m/k) … Equation [3] Pendulum: The restoring force in an oscilating Pendulum does not obey Hooke’s Law. F = -mgsinɵ … Equation [4] For the case of a small angle, small angle approximation can be used : sin ɵ ≍ ɵ, In effect, the equation will obey Hooke’s Law as shown in Equation [5]…

All fluids have its resistance to relative motion between surfaces and is called Viscosity. This property is about the friction between the particles of a fluid. A fluid that is forced in a tube has the liquid moving faster as it is closer the axis of the tube and slower when farther from it. 3.1.1 Dimensionless Parameters In analysis of convection heat transfer, it is convenient to convert to non-dimensional the governing equations and combine the variables, which makes the group of…

Introduction and Overview: For this extended essay, I will be working on building and optimizing different sized water rockets to find out the optimum amount of fuel (water) for each the different rocket sizes. I will be measuring the ranges at which each rocket will fly to find out the optimum fuel level. A brief summary of water rockets: A water rocket is made up of a selection of parts to provide its successful launch: the nose cone which will make the rather snub-nosed end of the large…

LINEAR WAVE THEORY Linear wave theory can be defined as first-order, small amplitude gravity wave with a sinusoidal shape. This theory has been developed by Airy in 1845. It is easy to apply and give reasonable approximation of wave characteristic for a wide range of wave parameters. However, in some situations, waves are better described by higher order theories or also referred as finite-amplitude wave theories. Although there are limitations to its application, linear theory is still useful…
