Lecture
This lecture covers the angular momentum theorem for a fixed axis of rotation, focusing on forces and moments that maintain the rotation. It also delves into the dynamics of a solid with a fixed axis, using examples like the physical pendulum to illustrate concepts such as concentrated mass and gravity. The lecture further explores the center of percussion calculation, vector components of angular momentum, and rotating axes in Euler's equations. It concludes with discussions on free rotation of solids, inertia frames of reference, and relative motion in mechanics.
