I got this pulley question in class and i absolutely don't know howo to solve it.
Basically there's a 100lbs block (suspended in air) that is being held up by a pulley on top and the rope is anchored on the other side.

Your help will be greatly appreicated.
thanks!!

That 100 lbs block is attached with a rope to that pulley (the "o") and anchored down to that anchor (the "T"). the block is also suspended in air.


The question is "how much weight is being held by the pulley?"

Look at how to compute your mechanical advantage of your pulley.
