Key Concepts

Bending Moment Diagram

A graphical representation that depicts the bending moment along a beam at every point, which is critical for assessing how beams respond to loading.

Center of Gravity

The point in a body or system where all of its weight is equally balanced or distributed, crucial in determining stability and dynamics.

Mass Moment of Inertia

A measure of an object's resistance to rotational motion about an axis, impacting how loads are distributed within structures.

Fundamental Equations of Statics

Equations derived from Newton's laws of motion, used to solve for unknown forces and moments in static equilibrium.
