What is the moment for this diagram?

$M = F.S$ and $M = -F^2.S$

What is the moment for this diagram?

I am getting two moments; $M = F.S$ and $M = -F^2.S$

I am getting confused.

1 Check the dimensions

2 moment is wrt an axis -- you don't mention the axis

 

[Benjamin_harsh]

I think answer is $\sum M = 2.F.X$.

 

[haruspex]

I think answer is $\sum M = 2.F.X$.

As BvU noted, you must define your axis.
Is X the same as S?

 

[BvU]

I think answer is $\sum M = 2.F.X$.

If you don't define an axis of rotation, your statement is meaningless.

Do you know the defnition of moment ?
