Question

Draw the diagram of a single movable pulley and obtain its mechanical advantage, velocity ratio and efficiency
​

Answer 1

Answer:

which diagram can U understanding

Answer 2

1. Answer:
2. Since it is inconvenient to apply the effort in upward direction a single fixed pully is used to change the direction of effort .
3. Explanation:
4. In equilibrium, L=T+T=T2. E=T mechanical advantage =Load/effort =2T/=2 as the effort is pulled down through a distance de, the two segments of the thread carrying the moveable pulley and the load goes up by de/2 hence, dl=DE/2 velocity ratio(vr) =DE/DL =DE/DE/2=2 efficiency =MA/VR=2/2=1or100%
