An ideal block‑and‑tackle system has four supporting rope sections, giving an ideal mechanical advantage of 4. The system operates with an overall efficiency of 85 %. A load of \(800\ \text{N}\) is to be lifted. (a) Calculate the force the operator must apply. (b) If the operator can sustain a maximum force of \(250\ \text{N}\), determine the greatest load that can be lifted safely with the same system.

Answer Options

A. Force required \approx 250\ \text{N}; maximum load = 850\ \text{N}
B. Force required \approx 235\ \text{N}; maximum load = 800\ \text{N}
Correct Answer C. Force required \approx 235\ \text{N}; maximum load = 850\ \text{N}
D. Force required \approx 200\ \text{N}; maximum load = 850\ \text{N}
Correct Answer
C
Correct Option:
Force required \approx 235\ \text{N}; maximum load = 850\ \text{N}
