A roof system consists of trusses of the type shown in the figure below, spaced at 20 feet apart. Purlins are to be placed at the joints and at the midpoint of each top chord member. Sag rods will be located midway between trusses.. The total gravity load, including an estimated purlin weight is 20psf of roof surface, with a live load to a dead load ratio of 1.0. Assuming that this is the critical loading condition, use A 36 Steel and select a channel shape for the purlins. Use
