The objectives of this video are to introduce moment of inertia concept & to look at standard shape. The moment of inertia, also known as the second moment of area, is basically a geometric property related to some object resistance to rotational movements. In civil engineering, it is often combined this geometric property with material properties to determine physical quantities such as stiffness. Moving on, the video briefly talks about the unit of moment of inertia.
Next, the video introduces with Ix and Iy- Ix is related to the rotations relative to x axis & Iy is related to the rotations relative to y axis. Later, the video introduces with the standard moment formulas of rectangular and circular shape objects explaining all the facts and figures in greater details. Overall, the video tries to clear the concept on moment of inertia- understanding which is very important in doing many workouts of engineering mechanics.
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.
