The objective of this video is to work out on moment of inertia of simple shape. First of all, the video shows a rectangular shape of 400 mm by 200 mm & asks to find the moment of inertia with respect to x and y axis. Next, the video briefly illustrates the given rectangular structure discussing the facts of finding moments of inertia with respect to reference axes and consequently introduces with the required formula to calculate Ix & Iy- Moving on, the video shows how to determine the moment of inertia with respect to x and y axis from the dimension data available.

Second part of the video shows another workout of finding moment of inertias for circular shape. In this example, the diameter of the circle has been given as 50 mm. The video moving next introduces with the equations required to calculate Ix & Iy that have been overviewed in previous video & finds out the values of moment of inertias successively. Later, the video refers to watch next videos for composite bodies’ workouts and to get in touch with parallel axis theorem.

Course Description

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.
