This video briefly works out on solving an example using the principle of equilibrium and free body diagram. First part of the video asks to imagine a simply supported beam having a point support at left end and a roller support at right end. Next, the video talks about the data given e.g., distance between two ends of the beam and a bending moment acting clockwise over the beam at certain distance from left end. The video asks to consider black colored diagram only ignoring blue colored reactions that are actually unknown and needed to be calculated down using equilibrium method.
Moving on, the video explains the first step of solving the problem which is the drawing of reactions forces on the FBD; subsequently in next step shows how to establish equilibrium using the different components of forces and moments acting over the given simply supported beam. In last step, the video shows the solution procedures of the established equilibrium condition & thereby found out the unknown value of different reaction forces.

Course Description
This course builds on the concept of force and moment equilibrium learnt from first year engineering mechanic and physics courses and focuses on the internal actions and deformations experienced by simple structural members under loading. Concepts learnt in the course such as load transfer through axial, shear, bending and torsion as well as stress and strain relationships are the foundation for further study in any structural engineering related courses.
