The roof truss shown is typically used for solar energy purposes, where a near normal angle of incidence of sunlight onto
the south-facing surface ABC is desired. The 5 vertical loads represent the effect of the weights of the truss and
supported roofing materials. The load F2 represents the effect of wind pressure. Determine the x-intercept (in m,
roundoff to 2 decimal places) of the line of action of the system resultant treated as a single force R.
