Taschenbuch. Etat : Neu. Neuware - Have you ever walked through an automatic door and wondered how it knew you were there Why does a gas pump stop before the tank overflows How can an elevator stop perfectly level with the floor-or a smoke detector sense danger before you see flames The machines surrounding us perform remarkable feats every day, yet most of their cleverest engineering remains hidden behind metal panels, plastic covers, walls, and ordinary-looking buttons.How Does That Actually Work takes you inside 25 familiar machines and reveals the fascinating science that keeps the modern world moving.Through engaging explanations and detailed, realistic illustrations, you'll discover: - How automatic doors detect you and open safely- Why an elevator needs a counterweight- How an escalator's steps continuously disappear and return- Why refrigerators don't actually 'make cold'- How washing machines recognize an unbalanced load- Why microwave ovens heat food unevenly- How smoke detectors detect invisible particles- Why pressure cookers change the rules of boiling water- How traffic lights respond to real traffic- Why gas pumps automatically shut offEach chapter transforms an ordinary object into a captivating engineering story. Follow the hidden paths of force, heat, pressure, airflow, electricity, sensors, and feedback as everyday machines detect, decide, move, and protect.The explanations are clear and approachable-no engineering degree, complicated equations, or technical background required. Realistic cutaway-style artwork helps you visualize what is happening inside each mechanism while the writing connects every component to the larger system.Perfect for curious adults, teenagers, students, educators, future engineers, and anyone who has ever taken something apart just to see what was inside.After reading this book, automatic doors, elevators, refrigerators, traffic lights, and even toilets will never look ordinary again.Open the book. Look beneath the surface. Discover the brilliant engineering hiding in plain sight.…
