## Homework Statement

If the engine thrust is F(T)=130kN and the plane's weight is W=180kN,determine the atmospheric drag F(D) and the wing lift F(L).

What is the distance s to the line of action of the drag force?

## The Attempt at a Solution

Well I have trouble with this question because I don't know where to start.In my statics book there is nothing on airplanes or about drag,thrust and lift.

I was thinking like the resultant force = F(T)- F(D)

I don't know the relationship between the drag,thrust and lift and couldn't find anything in my statics book.

So any hint or advice how to start it would be greatly appreciated or is there any equation I need to use.

Thanks.
