Help on this moments question?

Can someone tell me how you're supposed to find the moment about A? The answer's supposed to be 9.39 N in the clockwise direction but I can't get that

Perpendicular distance * Force

Clockwise $M(A): 4.6 \cdot 1.9 + 2.1\cdot 5.2$

Anticlockwise $M(A): 1.3 \cdot 7.9$

Find the resultant moment.

Thank youuuuuuuu but can I ask why you'd calculate the moment of the 5.2N and 7.9N forces? I thought they were acting parallel to A?

They are, and they have an effect on A. What about them?

Ohhhh never mind I was just confused

Perpendicular distance * Force

Clockwise $M(A): 4.6 \cdot 1.9 + 2.1\cdot 5.2$

Anticlockwise $M(A): 1.3 \cdot 7.9$

Find the resultant moment.

How do you know that the 7.9N force is anticlockwise but the 5.2 force is clockwise?

Observation. Imagine yourself having this contraption of whatever. Put one finger on A, and apply forces with the other hand on their respective positions. In which direction do you think will the contraption turn?? That's how I do it anyway, I'm quite visual with this stuff.

The only forces you can ignore are those acting from A, so like the 6.4N, if that's what you're asking.
