Alright, folks, let’s bounce into the world of springs! 🐰🌼 Ever wonder how springs decide whether to be bouncy Tiggers or more chill Eeyores? Well, it’s all about their spring rate! With our Spring Rate Calculator, you’ll discover the secret formula that determines whether your springs are more “boing” or “sproing”!
# Spring Rate Formula
spring_rate = force / displacement
