In this unit, you will learn how some small, human-powered mechanical devices work. You will see that tools as simple as a pair of scissors function on the same principles as massive equipment powered by fluid pressure and heat engines. You will discover the main factors in the efficient operation of mechanical systems. You will also design and build your own mechanical devices — including some powered by hydraulics and pneumatics — and investigate their efficiency. Finally, this unit examines how machines have changed as science and technology have changed.
