Question

A balanced lever has two weights on it, the first with mass `16 kg` and the second with mass `3 kg`. If the first weight is `7 m` from the fulcrum, how far is the second weight from the fulcrum?

Answer 1

`112/3m`

Explanation:

Well, if the lever is balanced, the torque (or, the moment of force) has to be the same. Hence,

`16*7m = 3*x`

`=> x = 112/3m`

• why can't I have some nice numbers, in the problem so that, at least the results look nice ??
