Abstract: A connecting rod is a major engine part that transfers motion from the piston to the crankshaft and functions as a lever arm. Connecting rod is used for transferring the reciprocating motion of the piston into rotary motion of the crank shaft. It is used to connecting piston and the crankshaft. In this study a connecting rod made up of copper alloy is modeled and analyzed. The properties of the connecting made up of copper alloy are compared with existing connecting rod made up of steel.
