Extracted text: Prob. 2.2-11. A rigid, weightless beam BD supports a load P and is, in turn, supported by two hanger rods, (1) and (2), as shown in Fig. P2.2-11. The rods are initially the same length L= 6 ft and are made of the same material. Their rectangu- lar cross sections have original dimensions (w, 1.5 in., 1, = 0.75 in.) and (w, = 2.0 in. t, 1.0 in.), respectively. (a) At what location, b, must the load P act if the axial stress in the two bars is to be the same, i.e., a, = o,? (b) What is the mag- nitude of this tensile stress if a load of P = 40 kips is applied at the location determined in Part (a)? 4.5 ft (1) (2) 6 ft Rigid, weightless C D.
