UGEARS - Pendulums 3D Wooden Puzzle Model - 92 Parts

The UGears STEM LAB is a NEW collection of educational mechanical models for children and adults that will give you a hands-on experience and make you more familiar with a science like physics or engineering. Learn about items of common use like gears and transmissions as well as their practical application in real life. STEM LAB model kits provide you with many hours of pleasure, turning the acquisition of knowledge into a joyous experience for both children and adults., The pendulum is a straightforward and reliable device for timekeeping. Its working principle is based on the model's constant oscillation amplitude caused by the force of gravity (weight) and the potential energy of the rubber band. The rubber band powers the mechanism of the model and compensates for the kinetic energy loss while the pendulum oscillates. The device is driven by means of a gear unit with a wind-up wheel., The mechanism of the Pendulum is composed of: an escapement wheel, a needle indicator, the pendulum itself with the anchor, a pendulum bob. Parts count: 92, Assembly time: 1-2hrs, Package includes: wooden boards with pre-cut parts and other supplies, a pocket models study guide.
