A block‑and‑tackle arrangement consists of one fixed pulley and one movable pulley, giving an ideal mechanical advantage of 2. It is used to lift a load of \(200\ \text{N}\). The system is operated at constant speed and has an overall mechanical efficiency of \(80\%\). (a) What is the tension in the rope? (b) What is the magnitude of the force that must be applied by the person pulling the rope? (c) How far must the rope be pulled to raise the load through a vertical distance of \(0.50\ \text{m}\)?

Answer Options

Correct Answer A. T = 125 N, \; F_{pull} = 125 N, \; d_{pull} = 1.00 m
B. T = 100 N, \\; F_{pull} = 100 N, \\; d_{pull} = 1.00 m
C. T = 125 N, \\; F_{pull} = 156 N, \\; d_{pull} = 1.25 m
D. T = 150 N, \\; F_{pull} = 150 N, \\; d_{pull} = 0.80 m
Correct Answer
A
Correct Option:
T = 125 N, \; F_{pull} = 125 N, \; d_{pull} = 1.00 m
