THINK #23 ENGINEERING CONSIDERATIONS:
Understanding what's inside
What is a schematic? It’s a drawing or a model of all the stuff that makes a product work. Work in the sense of function. It’s the bell inside the wind up timer, that’s connected to something that’s connected to the spring that’s connected to the knob that the user turns to set the time on the face that’s connected to the shaft. It’s all that stuff that makes the timer work and tick and including the sound of the bell.
