Beam deflection calculates downward displacement under loading. Engineers use this to ensure beams don't sag excessively and meet serviceability requirements.

Why limit beam deflection?
Excessive deflection causes floor sag, cracks, misalignment. Building codes limit deflection to L/240-L/360.
How does moment of inertia affect deflection?
Doubling I reduces deflection by half; this is why tall I-beams resist deflection better than wide ones.
