Given Data
- Mass of the stage: 500 kg
- Number of persons: 6
- Mass of each person: 60 kg
- Height lifted: 10 m
- Gravitational acceleration (g): 10 m/s²
- Time taken to lift: 20 s
Total Mass Calculation
- Total mass of the stage and persons:
- Stage: 500 kg
- Total mass of persons: 6 * 60 kg = 360 kg
- Total mass = 500 kg + 360 kg = 860 kg
Force Calculation
- Weight (Force) = Total mass * g
- Weight = 860 kg * 10 m/s² = 8600 N
Work Done Calculation
- Work done (W) = Force * Distance
- W = 8600 N * 10 m = 86000 J (Joules)
Power Calculation
- Power (P) = Work done / Time
- P = 86000 J / 20 s = 4300 W
Power of Motors
- Since there are 2 motors, power of each motor:
- Power per motor = Total power / Number of motors
- Power per motor = 4300 W / 2 = 2150 W
Conclusion
- Each motor must provide a power of 2150 W to lift the stage with the persons in 20 seconds.
