This updated second edition brings the complex mathematics of three-dimensional dynamics to life with real-time simulations, making the equations easier to grasp. Covering core topics in mechanical engineering such as kinematics, dynamics, vibration analysis, gyroscopes, gears, and Euler's equations, the book offers a clear and engaging approach for students, professionals, and enthusiasts alike. With a focus on practical applications, it explains everything from the laws of motion to motors and mechanisms, providing a comprehensive understanding of mechanical systems. New to this edition is a chapter on Power, Energy, and Perpetual Motion, which reveals intriguing comparisons, such as the energy needed to lift water versus the heat required to warm it. The final chapter, Rocket Science, has been expanded to debunk myths about black holes and gravity, humorously addressing science fiction misconceptions while proposing exciting space projects.
