The asymmetric roof truss is of the type used when a near normal angle of incidence ofsunlight onto the south$-$facing surface ABC is desirable for solar energy purposes. The fivevertical loads represent the effect of the weights of the truss and supported roofing materials.The $400-$N load represents the effect of$\text{'}$ wind pressure. Determine the equivalent force$-$couplesystem at A$.$ Also, compute the x$-$intercept of the line of action of the system resultant treatedas a single force R$.$The asymmetric roof truss is of the type used when a near normal angle of incidence ofsunlight onto the south$-$facing surface ABC is desirable for solar energy purposes.
