The video tutorial explains internal forces in structures, focusing on shear force and bending moment. It begins with an introduction to internal forces and the use of free body diagrams to identify reaction forces. The tutorial defines shear force and bending moment, explaining their roles in maintaining static equilibrium. Standard conventions for these forces are discussed, including their variability based on distance from a reference point. The video concludes with methods for plotting shear force and bending moment against distance to analyze their behavior.
