Mechanical governing typically involves the use of mechanical devices to control the speed of a turbine or engine based on physical changes in the system's operation. While mechanical governors can function adequately in many applications, they often lack the precision required for large turbines that demand tight speed control.

In the context of large turbines, such as those used in power generation, electronic or digital governors are preferred. These advanced systems offer better responsiveness and accuracy in maintaining the desired speed, especially under varying load conditions. They utilize sensors and control algorithms that can adjust for changes more dynamically than mechanical systems can.

Therefore, the statement suggests a reliability and suitability of mechanical governing for large turbines requiring precise speed control, which is not accurate given the need for highly responsive and precise control in those applications. This is why the answer indicating that the statement is false is accurate.
