This video, continuing straight from the previous video, very first clears its objective to find out the moment of inertias with respect to x axis. First part of the video presents the parallel axis theorem formula once again and focuses on finding the moment of inertia with respect to individual section centroid axis as input to the equation of finding moment of inertia with respect to shape centroidal axis. The video splits the given composite bodies into two shapes and once after another shows how to find the moment of inertia for them explaining all the facts in greater details.
Moving next, the video sums the moment of inertias for two split shapes and finally determines the moment of inertia for the given exemplary composite body. Later, the video briefly talks about few notes regarding the obtained values of moment of inertia successively elaborating the bending case of the composite body. It is highly suggested to do on hand practice to have better understanding on the workout done in this tutorial. Make a contact, if you don’t understand any part of this tutorial.
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.
