Combining Mechanisms: Building a Chain of Motion

Real machines almost never use one mechanism on its own, they chain several together.
The rule that makes a chain work is simple: the output of one stage becomes the input of the next.
The four motions and the five mechanisms are the alphabet, and combining them is the language a designer actually writes in.

Note

Complex systems combine different types of motion and several mechanisms at once.
They do this to perform a task that no single mechanism could achieve on its own.

Following the Chain Through a Bicycle

The rider's legs supply reciprocating motion, pushing down alternately.
The cranks turn that into rotary motion at the pedals.
The chain and sprockets carry that rotation to the rear wheel, and the gear ratio decides whether it arrives as speed or as torque.
The wheel converts rotation back into linear motion of the whole bicycle along the road.
