The objective of this video is to consider centroid of composite shapes. First of all, the video talks about the theory of splitting complex area into a number of simple shapes to determine the centroid location in easier way. The video, then, presents an L-beam shape & asks to find out the location of centroid of the given beam. Using the theory of splitting complex area, the video shows how to split the given L-beam shape into two simple rectangular shape and subsequently find out the location of centroid using the coordinates formulas overviewed in previous video.

Moving on, the video presents another comprehensive workout of composite shape example where the video asks to find the centroid position of a given exemplary I-beam. The video splits the I-beam into three simple rectangular shapes and subsequently determine the location of centroid similar to before. Overall, the video tries to give a brief overview on how to calculate the position of centroid of different composite shapes in solving many problems of engineering mechanics.

### 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.
