0.1 Mechanical Engineering Science covers various fundamental concepts that are essential in the practice of mechanical engineering. The title is comprised of 19 chapters that detail various topics, including chemical and physical laws. The coverage of the book includes Newtonian laws, mechanical energy, friction, stress, and gravity. The text also discusses the chemical aspects of mechanical engineering, which include gas laws, states of matter, and fuel combustion. The last chapter tackles concerns in laboratory experiments. The book will be of great use to students of mechanical engineering. The text will also serve professional engineers as a reference.
