Answer:
The answer to this question can be defined as follows:
Step-by-step explanation:
Advantage:
- The load can be raised with one fixed pulley by adjusting the shifting pressure path. 
- Its a fixed input pulley doesn't even have a mechanical advantage, the movement is larger than for the load. 
- It is preferable to use because the pulley must not be moved up or down. 
- It gains the measurement of just an increase in output power-to-input force ratio.
