Which term relates to the mechanical requirement to supply more power when using cable-based drive systems?

• A. Drive Unit
• B. Rack and Pinion
• C. Horsepower Requirement
• D. Chairlift Operation Inspection

Answer: (C)

The main idea here is how much power the drive must supply to move the system, especially under load. In a cable-based drive, the motor has to deliver enough power to overcome the weight of the car and passengers, plus friction and any acceleration or starting resistance. The term that describes this needed amount of power is the horsepower requirement. Since power equals torque times rotational speed, heavier loads or higher speeds mean the motor must deliver more power, so the horsepower requirement rises. That’s why motor sizing and performance are all about meeting this horsepower requirement: it ensures the system can start moving, start up smoothly, and sustain motion under the expected loads. The other options refer to a physical component (drive unit), a different drive mechanism (rack and pinion), or a maintenance task (chairlift operation inspection), none of which describe the amount of power needed.
