What is the machanical advantage of this system?
What system?
Hard to say. If you tried to copy and paste, that does not work here.
To determine the mechanical advantage of a system, you need to know the input force (the force applied to operate the system) and the output force (the force exerted by the system). The mechanical advantage can then be calculated by dividing the output force by the input force.
In order to provide a specific answer to your question, I would need more information about the system you are referring to. Could you please provide more details about the specific system or describe its components?
Once I have that information, I can help you calculate the mechanical advantage.
