Output force can only equal input force in a system where there are no losses. In the "real world" we live in, there are losses in every system, and that means that output force can nerver equal input force.
The mechanical advantage is the ratio of the output force to the input force. MA = output/input (output force divided by the input force) For the example, 15N/30N gives the MA as 0.5 (one half).
In a closed system in the "real world" in which we live, there are losses associated with friction and other actions. These forces "take energy" from the system between its input and output. When we apply force to the imput of a system, some is lost as the force is transferred through that system. That means that the output force we observe will always be a bit less than the input force. A transmission in a vehicle is a classic example of the idea that there are losses between the input and the output of a system. The input from the engine will always be a bit greater than the output at the tailshaft (or axles for a transaxle) due to losses within the transmission.

Depends what the input force is and the mechanical advantage of the pulley system If effort force (input force) is 20 pounds in a 6 pulley system (3 fixed,3 movable) then load force (output force) is 120 pounds As 6 times 20 equals 120 pounds

Not ever. There will be losses in the system no matter how clever it gets.
No they do not. An endergonic reaction requires a net input of energy to force it to occur.
It is when a system is accompanied by or absorbs heat. It requires an input for its formation from its constituent elements.
