The Scotch yoke mechanism, also known as a crank-rocker mechanism, is an engineering design that converts rotational motion into linear motion by using a back-and-forth rocking motion. This mechanism is commonly used in various applications such as actuators and pumps, where linear motion is required for operation. The name "Scotch yoke" is believed to have originated from Scotland, where this mechanism was first utilized extensively in textile machinery.
