When you have more pulleys does the mechanical advantage and efficiency increase or decrease?
Answered by bobpursley
Ma increases. Efficiency normally is reduced, as friction is a significant loss.
Answered by Jordan

Answered by bobpursley
efficiency is unchanged, and everyone lives happily forever.
