Force resolution in physics is a fundamental concept that involves breaking down a force into its horizontal and vertical components using trigonometry. This technique simplifies the analysis of statics problems, equilibrium conditions for concurrent forces, and internal force analysis in truss structures. Understanding how to apply these principles is crucial for designing stable structures and solving complex engineering problems.
