A spiral torsion spring functions by storing energy through the twisting of its coils, which creates potential energy that can be released to perform work. The physics behind it involves torque and angular displacement, where the spring's resistance to twisting is proportional to the angle of twist. For detailed information, resources such as physics textbooks, engineering websites, and academic articles on mechanical springs are recommended. Understanding the mechanics of a diving board can also provide insights into how energy is stored and released in similar systems. Exploring these resources will clarify the principles of spiral torsion springs and their applications.
