Physics question need help urgently! Kinematics

Hi everyone, so my teacher gave us this test and told us to complete it by Friday.
I've attempted the Free Body Diagram (FBD), but have no idea where to go from there, im not even sure if the FBD is even correct.
Please help! Thank you!

Certainly doesn't look like a typical physics question.

You draw arrows FROM the point of application, not to it.
I think you should draw all the arrows originating from the centre

You find the resultant force by considering east/west and north/south forces separately, for example Force1 would be 60cos(pi/6) N west and 60sin(pi/6) south; then you add the east/west and north/south forces together to get an overall east/west force and north/south force, then use Pythagoras to find the net force.

The point of application is probably the centre

4. either centre, or centre of mass

I want someone else to see if what I said is right, since this problem is really weird

I don't think any of the directions of the forces are given, so this question can't really be done without assumptions.
