A 17' span is pretty big too. This sounds to me like something that's illegal to do without a licensed structural engineer. So I'm...

Lnewqban replied to the thread I 1:1 versus 2:1 Mechanical Advantage debate.I respectfully disagree. What we have in this case is a balanced mass hanging from two ropes, in successive steps. The only function of...

Lnewqban replied to the thread I 1:1 versus 2:1 Mechanical Advantage debate.Welcome, @cmars ! Perhaps it is not completely correct to call it mechanical advantage. The fixed pulley, which is the only device in...

Your self-haul with a single fixed pulley has a 2:1 MA in the ideal case: half the force, twice the rope. The confusion clears the...
