Question

What is the mechanical advantage of a pulley system​

Answer 1

Answer:

Pulleys accomplish 2 separate operations throughout the computer controlled additional benefit technologies listed elsewhere here.

Explanation:

• If indeed the pulley would be connected to that same attachment point, these are named a corrected pendulum or perhaps a change in direction. Its job should be to reverse the trajectory of that same rope pull.  
• Unless the pulley would be connected to that same load, this same pulley seems to be a detachable as well as a mechanical additional benefit.
