Reactions of Simply Supported Beam under Point Loads I Lecture 1 I Solid Mechanics I Arijit Banik

In this lecture, we discuss the fundamental concepts of beam reactions, focusing on statically determinate beams and the calculation of support reactions for simply supported beams under point loads. The session begins with an explanation of what statically determinate beams are, how to identify different types of supports, and how to calculate the degree of static determinacy using equilibrium conditions. This forms the theoretical foundation required for analyzing beam reactions. In the second part of the lecture, we demonstrate the step-by-step procedure to calculate support reactions of simply supported beams subjected to point loads, using: Free Body Diagrams (FBD) Equations of equilibrium (ΣFy = 0, ΣM = 0) Proper interpretation of load positions and distances The lecture also includes active learning exercises and practice problems designed to improve conceptual clarity and problem-solving skills. This video is particularly useful for UG Civil Engineering students, first-year engineering courses, and those preparing for semester examinations and competitive exams. 📌 Topics Covered: Statically determinate beams Degree of static determinacy Types of supports and reactions Simply supported beams Reactions under point loads Numerical problem solving 📘 Course: Solid Mechanics / Engineering Mechanics 🎓 Target Audience: Undergraduate Engineering Students
