Which term describes the governor's activation speed based on incline?

• A. Horizontal Speed
• B. Tripping Point
• C. Incline Speed
• D. Vertical Speed

Answer: (B)

In a governor system, the important idea is the point at which the governor activates to limit or reduce speed. When an escalator or moving walk runs on an incline, the load and torque change, which can shift the speed at which the governor reaches its activation threshold. The term that describes that activation threshold—the speed at which the governor trips to regulate the drive—is the tripping point. It captures the moment the governor engages to keep the system from overspeed.

Other terms refer to actual speeds in a direction (like horizontal or vertical) or to a general incline-related speed, but they don’t name the moment of governor activation. The tripping point specifically conveys the trigger speed that prompts the governor to intervene.
