The compound beam consists of the two solid steel rods bolted
together along their length. The beam initially positioned as
shown in (Figure 1) later was rotated 90° about the line of
touch of the rods, so that both rods rest on the supports at
A (pin) and B (roller), while the unchanged loading became
evenly distributed on both rods. Suppose that P = 70 kN.
