Torque = F x D

M

_{anticlockwise }= M

_{clockwise}

## The Attempt at a Solution

From what I understand, the moment on left hand side of the pivot point needs to be equal to the moment on right hand side, therefore...

(Fx.2)+(5x.14) = (7xd)

My initial thinking was to substitute 2N into F, so that both forces on either side of pivot point are equal to 7N. However, this was not correct because the resultant forces were not in equilibrium after checking.

The answer in the book was this:

[/B]

**Could someone explain to me why F wasn't factored into the working? The way I'm interpreting this is that there is no force acting at point F. Would this be a correct assumption?**
