Motion: The Four Ways Anything Can Move

A mechanical system exists to turn energy into movement, and every movement a machine makes is one of four basic types.
They are linear, rotary, oscillating and reciprocating.
Hold onto these four, because every mechanism in the rest of this topic is really a device for converting one type of motion into another.

Linear Motion

Definition

Linear Motion

Movement in a straight line, in one direction or back and forth.

Movement in a straight line, in one direction.
It is the simplest motion to picture and the hardest to produce, because most power sources naturally spin.

Example

Conveyor belts transport goods along a straight path.
Trains run linearly along their tracks.
Hydraulic pistons turn fluid pressure into straight-line movement.

Rotary Motion

Definition

Rotary Motion

Movement around a circular path or axis.

Movement in a circle around a fixed axis.
This is the motion motors and engines actually produce, which is why so many mechanisms exist to convert it into something else.
