Find the moment of this Force about point A.

A force of 1200N acts on a bracket as shown in the figure. Find the moment of this Force about point A. Find the moment of this Force about point A.



Solution: I successfully resolved given force like this:



I am confused at taking moments of components of 1200N force about point A. Here it looks like bracket is fixed. so I don't think any moment will produced.

Whether the bracket is fixed is irrelevant.

$1200\sin(30) \text{ N } \cdot (0.140 \text{ m}) - 1200\cos(30) \text{ N } \cdot (1.20 \text{ m})$
