Vibrating Cantilever Ruler

A steel ruler clamped at one end beneath a heavy book is pulled down and released, showing the resulting oscillation. The animation highlights simple harmonic motion in a cantilever system, illustrating how the fixed end stays still while the free end oscillates with decreasing amplitude due to damping. Useful for students learning about elasticity, restoring force, and mechanical vibration in introductory physics.
