## Mechanics Made Easy: How to Solve Mechanics ProblemsThe fascinating subject of mechanics provides an insight and the inter-relationships between mass, time, distance, velocity, momentum, acceleration, force, energy and power. In turn this improves our understanding of the workings of our everyday world. An effective way to learn about mechanics is to solve mechanics problems. "Mechanics Made Easy (How To Solve Mechanics Problems)" is designed to supplement standard introductory-level school, college and university texts on this subject. The book consists of over 300 mechanics problems and step-bystep worked solutions in twelve topics: Velocity and Acceleration Relative Motion Projectiles Circular motion Collisions Laws of Motion Jointed Rods Equilibrium Motion of a Rigid Body Hydrostatics Differentiation and Integration Simple Harmonic Motion Over 500 clear, concise diagrams are provided to assist understanding of both problems and solutions. Working through these problems can help the reader improve problem-solving skills and gain the confi dence to tackle similar questions. |
