The task is to identify the side view of a spring from the given options. A spiral or helical spring, when viewed from the side, generally appears as a series of parallel lines or bands because the coils overlap each other in perspective. Evaluating the provided images, we need to determine which figure represents the silhouette or side view of a spring.
Upon examining the images, Figure 1 is the correct representation of a spring's side view. It displays a sequence of lines that resemble the overlapping nature of coils in a spring when observed from the side.
