Reciprocating

Reciprocating motion is back and forth motion. In the example to the right the reciprocating motion of the piston is converted to the rotary motion in the crank.

 
Reciprocating motion is measured by its throw (the distance between the two extremes of motion) and by its period (the length of time for each cycle)
