The bracket, which is fastened to a wall by anchor bolts at A and B, is loaded by the force P = 140 N and the couple C = 180 N · m. Replace P and C with (a) an equivalent force-couple system, the force of which acts at A; and (b) two vertical forces, one acting at A and the other at B.

2. The asymmetric roof truss (Figure 1) is of the type used when a near normal angle of incidence of sunlight onto the south facing surface ABC is desirable for solar energy purposes. The five vertical loads represent the effects of the weights of the truss and supported roofing materials. The 400 N load represents the effect of wind pressure. Determine the equivalent force couple system at A. Also compute the x intercept of the line of action of the system resultant treated as a single force R.
