# A balanced lever has two weights on it, the first with mass #16 kg # and the second with mass #14 kg#. If the first weight is # 2 m# from the fulcrum, how far is the second weight from the fulcrum?

##### 1 Answer

#### Explanation:

The beam ends at the points of loading. It is not stated as such

The weight of the beam is discounted. No uniformly distributed load given.

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

For the beam to be in equilibrium (balanced and not moving)

All forces and moments cancel out.

Let clockwise moments be positive

Let anticlockwise moments be negative

A moment is

The force of the 'Reaction' has moment arm length of 0. So this cancels itself out giving only:

So for the system to be in equilibrium (not moving)
