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.""
