The objectives of this video are to give an introductory overview on how to use free body diagrams to deduce support reactions followed by a comprehensive workout on support reactions example. At first, the video illustrates a given diagram of simply supported beam having a pin support at left end and a roller support at right end and consequently shows the point load conditions acting over the beam. Next, the video explains the reactions forces exerted by the supports and draws the free body diagram for it successively deriving the equilibrium equations.

Moving next, the video presents an exemplary beam structure supported by pin and roller supports respectively at left and right edge and subjected to a uniformly distributed load and point load. The necessary dimensions & the subjected loads values are given. Using the given information, the video shows how to draw FBD & subsequently establishes equilibrium condition to find out the reactions forces value exerted by the supported bodies to the beam structure. It is highly recommended to do on hand practices to have good grasp on the content overviewed in this lesson.

### 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.
