*Solving Engineering Problems in Dynamics* helps practicing engineers successfully analyze real mechanical systems by presenting comprehensive methods for analyzing the motion of engineering systems and their components. This analysis covers three basic phases: 1) composing the differential equation of motion; 2) solving the differential equation of motion; and 3) analyzing the solution. Although a formal engineering education provides the fundamental skills for completing these phases, many engineers nonetheless would benefit by gaining further insight in using these fundamentals to solve real-life engineering problems. This book thus describes in step-by-step order the methods related to each of these phases.
