How is this possible? Someone tell me please.
2 single pulleys means 3 lengths of rope (one side to first pulley, first pulley to second pulley, second pulley to second side), hence a mechanical advantage of 3.
2 double pulleys has twice the number of lengths of ropes, so we have 6 lengths of rope, and therefore a mechanical advangtage of 6.
A single pulley by itself may or may not provide a mechanical advantage. My advice o you, clz2 - draw it.
Can you draw out your description? I am having trouble following the wording. I thought I understood what you said, but when I try to sketch it myself, I am a bit confused. I think that one side of the rope is attaching to the center of pulley one.
