Question

: So far, you’ve been working with an “ideal” pulley system. How do you think real pulley systems are different, and how would that affect the mechanical advantage of real pulley systems?

Answer 1

Answer:

To calculate the mechanical advantage of a pulley you simply have to count the number of rope sections that support whatever object you are lifting (not counting the rope that is attached to the effort). For example, in a one pulley system the MA is 1. In a two pulley system the MA is 2.
