The objectives of this video are to introduce the hydrostatic forces concept and to solve hydrostatic force on a submerged plate. At first, the video briefly talks about hydrostatic & hydrodynamics; two branches of fluid mechanics. In the study of hydrostatic, the effect of shear force is not considered. The only force that is considered is the force developed by the pressure of fluids. With that in mind, the video examines a pressure vessel that experiences hydrostatic forces thorough out its walls. The video, then, introduces with the equation of pressure force explaining all the facts in details.
Moving on, the video presents a workout on an exemplary problem where the resultant force on the metal plate at the bottom of the given tank has been asked to calculate down. The video step by step shows how to find the pressure developed in the bottom plate from the unit weight & height of the fluid and subsequently determines the resultant force acting on the metal plate at the bottom of the tank just by multiplying the obtained pressure with the cross-sectional area.
Mechanics, the study of forces and physical bodies, underpins a very large proportion of all forms of engineering. A thorough understanding of mechanics is essential to any successful engineer. This course helps develop an understanding of the nature of forces with consideration for how they may be simplified in an engineering context. The conditions of equilibrium are then used to solve a number of problems in 2D and 3D before moving on to a broad range of topics including centroids, distributed loads, friction and virtual work. The course will also provide an introduction to dynamics, with a particular focus on the effects that forces have upon motion.
