Action Origami Mastery Hub: The Industry Foundation Practice

Within the context of "The Complete Kinetic Origami Sculptures Course 2026," which fundamental principle of kinetic sculpture is most emphasized when transitioning from static origami to dynamic, self-actuating forms?

In "The Complete Kinetic Origami Sculptures Course 2026," when designing an origami mechanism that relies on a pre-tensioned spring-like fold for its primary actuation, what potential pitfall, if not addressed early, could lead to a loss of kinetic integrity over repeated cycles?

According to "The Complete Kinetic Origami Sculptures Course 2026," a "self-closing" kinetic origami module, designed to return to its original state after actuation, often utilizes a combination of opposing forces. Which of the following best describes the *primary* opposing force utilized in many such mechanisms to ensure a consistent and reliable return stroke?
