This up‎-to‎-date introduction to kinematic analysis ensures relevance by using actual machines and mechanisms throughout‎.‎ MACHINES & MECHANISMS‎,‎ 4/e provides the techniques necessary to study the motion of machines while emphasizing the application of kinematic theories to real‎-world problems‎.‎ State‎-of‎-the‎-art techniques and tools are utilized‎,‎ and analytical techniques are presented without complex mathematics‎.‎ Reflecting instructor and student feedback‎,‎ this Fourth Edition‎'‎s extensive improvements include‎:‎ a new section introducing special‎-purpose mechanisms‎;‎ expanded descriptions of kinematic properties‎;‎ clearer identification of vector quantities through standard boldface notation‎;‎ new timing charts‎;‎ analytical synthesis methods‎;‎ and more‎.‎ All end‎-of‎-chapter problems have been reviewed‎,‎ and many new problems have been added‎.‎
