Using the moon as a fulcrum, how long is Archimedes' lever?

If Archimedes can lift 60 kg, he would need a lever with an arm ratio of $10^{23}:1$. So if the short arm is one meter long, the lever length will be $10^{23}$ meters plus one. Also, note that he would have to push the lever for $10^{20}$ meters to shift the Earth just by one millimeter. read more

“Give me a lever long enough, a fulcrum strong enough and I’ll move the world” –Archimedes. No doubt both of you guys have heard the quote. My question is just how long of a lever would be needed, and where would the fulcrum need to be placed for an average human to lift the weight of the earth. read more

With a 100 lbs of pulling force using the Moon's apogee(252,088) as a fulcrum, Assuming"at Earths gravity" Archimedes would need a lever 3.32E+28 miles long. read more
