Determine maximum deflection, bending moments, and reaction forces for structural beams
Supports cantilever, simply supported, UDL, and point loads.
Excessive deflection can crack finishes, jam doors, or be visually unsettling. Building codes limit deflection (e.g., L/360) to ensure serviceability and safety.
Moment of Inertia (I) represents a beam geometry's resistance to bending. A higher "I" value (deeper beam) significantly reduces deflection.
