Key Concepts

Moment (Torque)

Moments, or torques, represent the tendency of a force to rotate a body about a pivot or axis. Understanding how to calculate and balance moments is crucial in the analysis of systems under load, as it ensures that not only are the linear forces in balance but also the rotational effects produced by those forces.

Free-Body Diagrams

A free-body diagram (FBD) is a graphical representation that isolates a body and depicts all the external forces and moments acting on it. FBDs are essential tools in mechanics because they help visualize the problem, identify all the forces involved, and set up the corresponding equilibrium equations.

Equilibrium Conditions

In statics, a system or body is in equilibrium when the sum of all external forces and the sum of all moments (torques) acting on it are zero. This principle is fundamental for solving problems that involve balancing applied loads, such as determining reactions or internal forces within structures and mechanical systems.

Force Decomposition

Force decomposition involves breaking a force into its orthogonal components, usually along the horizontal and vertical directions. This method simplifies the analysis of forces acting at an angle, allowing the application of equilibrium equations to each independent direction.
