It has been said; "Give me a long enough lever and I shall move the world." How long does this lever need to be? a. Who is the quote from?_ b. Assume your weight (under an acceleration of 1 g) and the weight of the earth on the other side of a pivot (again under 1 g acceleration). We will use the moon as a pivot point. (Everyone knows the moon is 384000km away..) and I'm not sure where we will get it from but let's assume the lever arm is massless. Equate the 2 torques to find how far away you would have to be away from the pivot in order to counter balance the earths torque. c. Distance away = km d. I have a feeling Astronomical Units (AU) are a better unit.
