So the forces start at the point of the triangle and end on the base, is that right?

Thanks for replying!

Hi,
today while playing lfs I tried to discover what where the forces being applied to my car and I found it a bit confusing...

The car is making the normal blackwood circuit and I identified the forces so that you guys could easly refer them later.
Here is the image:


My questions are:
What is that middle force (force 3) and where is it pointing to?
Is the force 4 the gravity force exercised by the wight of the car on that wheel?
Is force 1 the friction exercised by the acceleration of the car?
Is force 2 the force exercised by the wheel while the car is turning (left in the image)?
Where does the forces start from the point of the triangle or the base?

Sorry for the image being so black.
And thanks in advance.
