Center of Percussion in Mechanics

This lecture delves into the concept of the center of percussion in mechanics, exploring the relationship between the geometry of an object, its various masses, and the point where it receives a percussion. Through practical examples involving a bar and a hammer, the instructor demonstrates how to find the optimal point to strike to prevent breakage at the articulation. By analyzing the impact of translation and rotation induced by a percussion, the lecture highlights the importance of choosing the correct point to achieve a balanced motion. Theoretical calculations and practical experiments are used to illustrate the principles behind determining the center of percussion and the moment of inertia, providing insights into the physics of collisions and rotations.
