Archimedes is supposed to have said, "Give me a place to stand on, and I will move the Earth." Suppose you had an object with a mass equal to that of Earth (5.98 1024 kg), and it experienced gravity equal to that at Earth's surface, so that its weight was 5.87 1025 N. If by using a lever you could move this mass with a force of 175 N, what would be the mechanical advantage of the lever?

Mechanical advantage is ration of two forces which shows how much greater force we can get as a result of using lever.

[tex]MA= \frac{ F_{a} }{F_{b}} [/tex]

We are given information:
[tex]F_{a} = 5.87* 10^{25} N \\ F_{b} = 175N[/tex]

[tex]MA= \frac{ 5.87* 10^{25} N }{175 N} \\ MA=3.4* 10^{23} [/tex]
