What is the function of a connection rod?

A connection rod, often referred to as a connecting rod, is a crucial component in internal combustion engines and some machinery. Its primary function is to connect the piston to the crankshaft, converting the linear motion of the piston into the rotational motion needed to turn the crankshaft. This conversion is essential for the engine's operation, as it enables the power generated from fuel combustion to drive the vehicle or machinery. Additionally, the connecting rod must withstand significant forces and stresses during operation, requiring it to be made from durable materials.
