Explore the mechanics of a bicycle pump and its pressure gauge in this detailed 3D animation. Learn how the pump uses two one-way valves to efficiently move air into the tire and how the pressure gauge measures air pressure. High-pressure air pushes a piston connected to a rack and pinion mechanism, which rotates an indicator arrow to provide a readout. This animation clearly demonstrates these processes, offering a deep dive into the functionality of these everyday tools.
