Product Details

This apparatus is designed to study the oscillatory motion of both simple and compound pendulums, allowing students to determine key parameters such as the period of oscillation, the radius of gyration, and the acceleration due to gravity. It provides a comparative analysis of how the pivot point and mass distribution affect the motion of a rigid body versus a point mass. The unit is a wall-mounted setup featuring a long pendulum bar that can be pivoted at six different points along its length to function as a compound pendulum. A movable mass on the bar allows for adjustment of the system moment of inertia. A separate long thread with a bob is included to model a simple pendulum. A digital stopwatch is provided for precise time measurement, and an attached ruler ensures accurate positioning of the pivot and mass. Its primary application is in physics and mechanical engineering education for teaching dynamics and vibration principles. The key benefit is the hands-on verification of theoretical models, enabling students to experimentally calculate g, understand the concept of the center of percussion, and grasp the differences between the oscillatory behavior of ideal and physical pendulums.
