you set up a pulley to help you lift something you anchor the rope at one end and arrange a moveable pulley to achieve a mechanical advantage of 2 by the time you have lifted the object 5m off the ground how much rope have you pulled through the pulley
answer is (10m)
The theoretical mechanical advantage is the ratio of the input force to the output force in a simple machine without accounting for energy losses due to friction or other factors. It represents the ideal mechanical advantage that a machine could achieve under perfect conditions.
The mechanical advantage of a machine indicates how much it multiplies force or velocity. A higher mechanical advantage means the machine requires less input force to achieve a certain output force, but it may trade-off by requiring more input distance. Ultimately, the work output of a machine is affected by its mechanical advantage as it determines the efficiency in transforming input work into output work.
To achieve a mechanical advantage of more than one, a trade-off usually involves increasing the distance over which the force is applied in exchange for a reduction in the amount of force required. This leverages the principle that work input must equal work output in a system.
As the size of the wheel increases, the mechanical advantage of the wheel and axle system also increases. This is because a larger wheel allows for a larger distance to be covered with each rotation, resulting in less force required to achieve the same work. Therefore, larger wheels provide a greater mechanical advantage compared to smaller wheels.
The force required to overcome friction between parts of a machine or device causes a difference between the ideal and mechanical advantage of the object. Friction reduces the efficiency of a machine by causing energy losses, making it harder to achieve the theoretical ideal advantage.

Mechanical device, parts in place to achieve something.
If you have an advantage you are in a better position to achieve something. For instance:- "The athlete with the longer legs had the advantage in the 100m hurdle race".

The ratio of a machine's output force to the effort applied is called mechanical advantage. It is calculated by dividing the output force by the input (applied) force. Mechanical advantage quantifies how much the machine can multiply the input force to achieve a greater output force.
Mechanical advantage measures the ratio of output force to input force, showing how much a machine amplifies force. Efficiency, on the other hand, measures how well a machine uses energy and is the ratio of output work to input work. A high mechanical advantage means a machine can achieve a large force output, while high efficiency means a machine minimizes wasted energy during its operation.
That is called mechanical advantage. It enables a person to achieve a greater output force with a smaller input force.
