Creating Mechanical Disadvantage with Pulleys

[ENGN3God]

Hey guys,

Is there a way to set up a pulley system that creates a mechanical disadvantage? My group and I are trying to produce a pulley system that, when a certain weight is attached, requires five times the amount of force to move the weight. I certainly know how to create a mechanical advantage, but what about a disadvantage?

Thanks!

Can you just use your mechanical advantage pulley backwards? switch which ends you pull on and attch the weight to? Just wondering...

That would be my approach, for sure. Anything that gives an advantage in one direction will give a disadvantage in the opposite direction.
