This section explores the Principle of Superposition, a fundamental concept in engineering and physics. It states that in a linear system, the net response caused by multiple stimuli can be determined by summing the responses that would be caused by each stimulus individually. This principle is crucial for analyzing systems in mechanics, electrical circuits, and wave propagation. Applications and implications of this principle in various fields will be discussed, highlighting its importance in simplifying complex analyses.
