Physics of sailing - Term Paper Example Introduction: Sailing refers to the act of controlling a vessel that is moving across a water body using the power of wing for propulsion. The act of successfully sailing a water vessel entails a lot of scientific principles worth studying. The scientific principles behind sailing vessels mostly consist of fluid mechanics phenomena of viscous fluids moving around fixed bodies (Anderson, 5). Various forces act on a sailing vessel that set it in motion and prevent it from sinking. Physics principles are used in the design of various parts of sailing vessels; therefore it is important to study the physics of sailing. This paper discusses the physics principles, including fluid mechanics that applies to sailing vessels and influences their design and operation. It reviews the forces acting on a sailing vessel and fluid mechanics of viscous fluids to detail the origin of the forces, lastly, various applications of the physics principles related to sailing a commercial uses of physics of s ailing are presented and discussed. Theory: This section presents the theory behind physics of sailing. First, we start by looking at the fundamental terminology relate to sailing vessels. The main parts of a basic sailing vessel are shown in the diagram below: Hull: this is the main body of the vessel that makes a boat. It determines the basic performance characteristics of the vessel such as maximum speed and acceleration that the vessel can achieve. Also, the shape of the hull determines the resistance experienced by the vessel as it moves through water and as a result its acceleration and movement in low winds. The shape of the hull and the keel also determines the vessel’s stability which is critical to the performance of the vessel on different angles of sail (Anderson, 7). Hull speed formula: we can either describe a wave using a cosine of sine function. Using the sing function, the amplitude of the wave is 0 at the point of origin and its equation is given by: Where y is the wave’s height at a horizontal position x and A is the amplitude of the wave above the normal water surface. x is small near the origin, therefore: Sin (2?/?)x ? (2?/?)x y= A (2?/?) x the ratio of y to x is y/x = A(2?/?) As the wave passes, the general surface particle motion on the water wave is represented below: The wave’s speed through water is V; the speed of the surface particle moving in circular motion is U and the sum of the two speeds gives the net speed. Considering the type of motion involved, the ratio of the vertical speed to horizontal speed is u/v and is equal to the ratio of y to x, therefore, u/v = y/x = A(2?/?) Applying the law of conservation of energy to the surface motion of water, the two energies in this case are kinetic energy (mv^2/2) and gravitational potential energy (mgh). The energy equation is, H= 2A = the vertical distance between the crest and the trough. 2mgA = 2mvu gA= vu u= A(2?/?)v gA = A(2?/?)v^2 The speed of the surface wav e, v is obtained as = This parameter is important for calculating the maximum speed of vessels among other situations. For instance, since waves of long wavelength travel faster than those of shorter wavelength, they take a shorter time to reach the shoreline. Sailors recognize that an impending storm is signaled by long waves and the storms always originate from where the waves are coming. In addition, long-wavelength waves

The proposal is an overview of what is required for the project research. It justifies the choice of this project and sets the objective for the research. The proposal identifies the most suitable approach towards achieving the aims of this project. The proposal, in order to be complete, draws out an estimated timeline for the proposed research and development of the entire paging system. NEW PAGING SYSTEM PROJECT DESCRIPTION The new paging system project seeks to create a new system for Tufts Health Plan that is network based and managed through use of servers. The new software will be installed on servers whereby clients who are authorized by the systems administrator will be able to page support staff and key heads of the department in case of trouble OBJECTIVE OF THE RESEARCH The objective for the research into the new paging system project is the development of a network based paging system that will enable fast efficient paging of staff members. The project aims to enable fast and agile communication among staff members of the Tufts Health plan. The project research seeks to solve the problems posed by the stand alone system. These problems include inefficient communication, slow response to emergencies. Time wastage brought about by needing to access the support desk in case of an event so that they can page the relevant parties. JUSTIFICATION OF THE STUDY The reason for choosing this project is to provide a system that can aide in the saving of lives and treatment of the sick. Therefore the new paging system will provide for users in the Tufts health plan a better means of com munication and paging framework for its staff. Cases of unattended emergency situations due to the standalone system will be reduced. Staff will be able to be notified from different points in the organization and thus work faster and more efficiently. It will enable the different departments in the organization to be able to deal with its own issues rather than try access the single point paging system at the support desk. APPROACH TO THE STUDY The approach to this project will be based on existing software development methodologies. The most suitable methodology will be determined with more in depth research into the problem. The beginning point of the project will be gathering requirements for the new system at the Tufts health plan and research on the exact needs of the different departments in the organization. The next step will be to analyse the requirements and develop feature lists for ease of development of use cases the system. After establishing a proper foundational sys tem analysis I will move into system design and develop the class diagrams and the whole design of the system accompanying them with appropriate logical diagrams. The next phase of the project will be the implementation and testing of the system, which will finally lead us to successful deployment of the system.(Pressman,2010) The presentation of the system will be the endpoint for the
