The trade-off when using a group of pulleys is primarily between mechanical advantage and increased complexity. While a system of pulleys can significantly reduce the amount of force needed to lift a load, it may also require more rope and increase the overall size and weight of the setup. Additionally, the added friction and potential for energy loss in the system can reduce overall efficiency. Thus, while pulleys can make lifting easier, they also introduce challenges in terms of design and practicality.
at the rock climbing place they use pulleys to keep you safe :D
tape, flagpoles, those things you use for rock climbing, and the pulleys the construction people use! :)
No
Many people use pulleys in their jobs. The rides like Supreme scream, which go vertically up and down have pulleys in them. Elevators have pulleys in them, and people who ship cargo use pulleys in their cranes.
Pulleys are considered part of the lever family because they operate on similar principles of transferring force. Pulleys use a wheel and axle system to redirect and amplify force, just like how levers use a rigid bar to do the same. Both pulleys and levers help make it easier to lift heavy objects by trading off force over distance.
I have no idea
Tree trimming uses combination pulleys. Also combination pulleys are used to lift engines out of cars to work on them. Some construction sites use them in places they cannot get a crane.

This depends on their intended use.
