It is required to perform a structural strength test for the wings of a new Unmanned Aircraft System (HA). Flight engineering department calculated the forces acting on wings as shown in below table. The length of wing is 1000 mm and loads are symmetric with respect to y axis. (left and right wings are symmetrically loaded) Each loading cable is connected to subsequent cantilever with a smoot pin bracket. Please find the position of x1, x2, x3 to apply the requested loads while keeping cantilevers in horizontal position. Show your calculation (and if assumptions) in details. Hint: draw FBD of each cantilever. Distance from end, mm 200 400 600 800 Load, N 400 150 250 800 x1 x2 x3
