Question

A balanced lever has two weights on it, the first with mass `1 kg` and the second with mass `9 kg`. If the first weight is `3 m` from the fulcrum, how far is the second weight from the fulcrum?

Answer 1

0.33 m

Explanation:

The torque or moment of each of the weights about the fulcrum is equal because the lever is balanced.
Torque= Fd
F= mg
`m_1gd_1 = m_2gd_2`
F - Force (mass x gravitational
acceleration)
`d_1 = m_2d_2/m_1`
(1kg)(3m)/9 kg
