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. Last edited by Ganesh Ujwal; June 14th, 2019 at 11:07 PM.

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