Is it easier to pull up or down to lift a weight on a single pulley systeM?
The force required is the same.
Hmm. Well, I was given and A and B answer so, it has to be one or the other. I was thinking it was lifting (A) since the force to pull (B) seems to require more force. I could be wrong. I really don't know the answer.
Err, I think I got an incorrect picture in my head of what is going on (which is why it helps to have a diagram!) If the "pull down" scenario is just a rope looped over a pulley, whereas the "pull up" scenario has a pulley on the object, there is a mechanical advantage in the second scenario and thus it is easier to pull up.
Thanks Russ, that was my guess too. Pull up vs pull down. Thank you!
