How Does It Work? #nn

This Westinghouse educational comic explains how various technologies work. Featured topics include the turbojet engine, with diagrams of its three main components (air compressor, combustion chamber, and turbine) and how hot gases spin the turbine at 17,000 revolutions per minute to create forward thrust. The issue also covers electric motors, explaining how they provide mechanical power for industrial and agricultural applications, and details the basic principles of radio technology, including Heinrich Hertz's discovery of electromagnetic waves, the function of the electron tube as the heart of radio broadcasting and reception, and how microphones convert sound into electrical audio waves that modulate carrier waves for AM and FM transmission.
