This book provides descriptions on the latest works carried out on the measurement in mechanical systems related to automotive and mechanical engineering. It covers measurements that use typical sensors like potentiometer, anemometer, torque sensor, force sensor and thermocouple. The book also explains the development of several prototypes and how the workability of these prototypes is measured. All of the prototypes covered in this book involve integration of mechanical and electrical system. Such integration is one of the most important elements that need to be grasped by engineering students/young engineers to face the challenges in Industrial Revolution 4.0.
