Physics position problem (Block on a flatbed)

[Alexis2020]

Homework Statement

static equilibrium?

Relevant Equations

I am not to clear on the direction

Homework Statement:
a flat bed being attached to a notch, the limit on the notch was 1500N, the flat bed was 1200N . The length of the flat bed is 14 m, at 12 m are the tires. How close can you put a 1400N block to the notch before it surpasses the weight limit?
Homework Equations:
I tired 1400N/1200N then Multiply by 12, but seems to miss the actual purpose of the problem

The description is most unclear, and the thumbnail sketch in the image barely legible. Was a diagram provided?
At a guess, the flatbed is supported in a horizontal position by the notch at one end and one axle through a pair of tyres at distance 12m from the notch. The flatbed continues 2m beyond the tyres. Is that correct?

yes.

 

[haruspex]

yes.

Then draw and post a large, clear free body diagram of the flatbed, showing all the forces on it.

A few issues there.
The 1200N is the weight of the flatbed. Which way does that force act on it?
We don't care about the forces on the tires (is that what the mg is?)
You are missing two other forces on the flatbed. What is holding it up?
