The objective of this video is to work out the equivalent hydrostatic force on a vertical tank wall. At first, the video describes the exemplary problem of a tank containing fluids in a 4 m by 4 m by 3.5 m volume space and asks to calculate the equivalent hydrostatic force developed on the shaded wall of the given tank as a result of pressure force developed by the fluid inside the tank. Moving on, the video calculates the pressure at top and bottom surface of the tank explaining the fact that how the pressure forces work at different depth of the tank.

Next, the video shows the conversion of bottom pressure force into a distributed line load & draws the triangular distributed loads FBD showing how resultant forces act on the shaded wall gradually increasing in value to the depth of the tank. Later, the video converts the triangular load into a point load and shows how it acts through the center of the shaded wall. Overall, the video tries to give a brief inside to the calculation procedures of hydrostatic forces in liquid vessels.

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.
