Bouyancy. The Archimedes Principle

Lecture Notes from the year 2015 in the subject Physics - Other, grade: 1.0, , course: Civil Engineering, language: English, abstract: The eBook discusses the Archimedes principle of buoyancy and the buoyancy equation in general. Application to the field of engineering was also expounded in order to show the relevance of the principle in the engineering context. Sample problems are presented to understand fully the application of the buoyancy principle of Archimedes. Analysis of whether a certain object will float or sink are then explained based on the buoyancy equation. Therefore stability of objects can be analyzed by applying the mentioned principle. The principle of buoyancy can be applied in floating objects such as ships and boats, submarines, hydrometer, balloons and airships and so many other real-life applications. 'A buoyant force is defined as an upward force (with respect to gravity) on a body that is totally or partially submerged in fluid, either a liquid or gas. Buoyant forces are caused by the hydrostatic pressure distribution.' 'When a solid object is wholly or partly immersed in a fluid, the fluid molecules are continually striking the submerged surface of the object. The forces due to these impacts can be combined into a single force, the buoyant force.' 'The buoyant force, which always opposes gravity, is nevertheless caused by gravity. Fluid pressure increases with depth because of the (gravitational) weight of the fluid above. This increasing pressure applies a force on a submerged object that increases with depth. The result is buoyancy.'

I am a Philippine registered civil engineer and registered professional secondary teacher. I had passed the Civil Engineers Licensure Examination of the Philippine Regulation Commission (PRC) with a general average of 85.45%. I have been working for 20 years in various fields of civil engineering both in the construction industry and in the academe. At present, I am working as a full-time professor of Far Eastern University (FEU) Institute of Technology. I worked with Daewoo Engineering and Construction Co., Ltd. as Civil Engineer/Quantity Surveyor for the construction of Safi Independent Power Plant Project in Safi, Morocco. In Safi Project, I am in-charge with the design review and incorporate changes and improvement in the Bar Bending schedule submitted by the subcontractors and site construction management which involves planning and supervision. I perform analysis to develop design solutions using computer softwares such as Structural Analysis Program (SAP), Structural Analysis Aided Design (STAAD), GeoSlope, Plaxis and AutoCAD2010. I also worked as Design Engineer in Duqm Drydock and Shipyard Project and as Civil Engineer in Sur Independent Power Plant (SIPP) Project both in Sultanate of Oman under Daewoo Engineering and Construction Co., Ltd. Moreover, I also have varied experiences in engineering education as College Instructor and Engineering Department Head in the University of Eastern Philippines Laoang campus from 2003-2007. I worked as Laboratory Technical Instructor in the Civil Engineering department of Salalah College of Technology (SCT) in Salalah, Sultanate of Oman in 2007-2008. Subsequently, I worked as Professor in the Civil Engineering department in Adamson University, Manila, Philippines. My last employment as a Professor was in Mizan Tepi University, Ethiopia, as an Associate Professor in civil engineering department. As a Professor in the academe, I provide significant contribution through quality education in handling civil engineering courses which also includes assisting the students in their research endeavors. In addition, I also had relevant experiences in various positions in the civil engineering industry such as, quantity surveyor, project engineer, project development officer and technical writer. I had completed the degrees in Master in Civil Engineering (MCE) and Doctor of Philosophy (PhD) in Educational Management with specialization on civil engineering curriculum.
