Together with the [[crank (mechanism)|crank]], the connecting rod converts the [[reciprocating motion]] of the piston into the rotation of the crankshaft.<ref name="Yamagata 2005 p. 207">{{cite book | last=Yamagata | first=H. | title=The Science and Technology of Materials in Automotive Engines | publisher=Elsevier Science | series=Woodhead Publishing in materials The science and technology of materials in automotive engines | year=2005 | isbn=978-1-84569-085-4 | url=https://books.google.com/books?id=7rekAgAAQBAJ | page=207 }}</ref> The connecting rod is required to transmit the compressive and tensile forces from the piston. In its most common form, in an [[internal combustion engine]], it  allows pivoting on the piston end and rotation on the shaft end.

The predecessor to the connecting rod is a mechanic linkage used by water mills to convert rotating motion of the water wheel into reciprocating motion.<ref>{{Cite book|title = Steam Automobile Vol. 13, No. 3|url = https://books.google.com/books?id=kaexwddMdNoC|publisher = SACA|language = en|first1 = Robert L.|last1 = Lyon}}</ref>

The most common usage of connecting rods is in [[internal combustion engine]]s or on [[steam engine]]s.
