Structural Mechanics: Shear Force and Bending Moment Fundamentals

Understanding how external forces affect physical structures is the cornerstone of mechanical, civil, and structural engineering. This text-based course guides you through the fundamental principles of mechanics of materials, teaching you how to analyze different types of beams and loads to accurately construct shear force and bending moment diagrams. You will start with essential definitions of forces, moments, and beam types before moving on to step-by-step written derivations and practical numerical problems. Learn to identify different types of beams, including cantilever, simply supported, and overhanging structures. Analyze various loading conditions such as point loads, uniformly distributed loads (UDL), and uniformly varying loads (UVL). Calculate internal shear forces and bending moments at critical points along a beam. Draw accurate Shear Force Diagrams (SFD) and Bending Moment Diagrams (BMD) using step-by-step mathematical methods. Relate manual calculation methods to modern structural design workflows and computational analysis. This course is designed for engineering students, technicians, and beginners looking for a solid foundation in solid mechanics, with no prior advanced engineering experience required.
