In this video, we discuss one of the fundamental concepts in structural engineering — supports and support reactions. A support is a structural element that holds a beam, column, or frame in place and prevents unwanted movement. The support reaction refers to the force or moment developed at a support in response to loads acting on the structure. Understanding why support reactions are needed is essential for ensuring the stability and equilibrium of any structure. The video clearly explains the types of supports such as hinged, roller, and fixed supports, along with their corresponding reactions, including vertical, horizontal forces, and moments. You will also learn about the importance of support reactions in maintaining structural balance and how incorrect assumptions can lead to design failures. Finally, the session connects these concepts to real-life civil engineering applications, including bridges, buildings, trusses, and frames, helping learners visualize how supports play a vital role in distributing loads and maintaining structural integrity. This lecture is perfect for civil engineering students studying Mechanics of Solids and Structural Analysis, providing both theoretical understanding and practical insight.
