modal superposition

Modal superposition is a concept often used in physics and engineering, particularly in the study of vibrations and structural analysis. It refers to the idea that complex movements or behaviors of a system can be understood as a combination of simpler, distinct modes of behavior. Each mode represents a unique way the system can vibrate or respond to forces. By analyzing these modes individually and then combining them, we can predict the overall response of the system accurately, making it easier to design buildings, bridges, and various mechanical systems to withstand loads and vibrations effectively.
