given a lever and a place to stand, Archimedes claimed to be able to move the earth. amusing he could use the moon as a privet point, how long would the lever have to be? (the earth moon distance is 382000km
toque = (force)(lever arm)
toque =I cross alpha
The Attempt at a Solution
i cant get my head round this at all, this is my "logic":
If Archimedes had somewhere to stand (outside the earth) then his acceleration/force he exerts could be anything depending on the mass of the body on which he is standing. In addition due to the earth and the sun being in essentially equilibrium would any small force from an external reference frame to the Earth move it albeit very slightly?
Any pointers as to the thought process i need to solve this would be of great help!
