Prob. 3.4-9. A rigid beam AB of total length 3 m is sup- ported by vertical rods at its ends, and it supports a down- ward load at C of P = 60 kN. as shown in Fig. P3.4-9. The diameters of the hanger rods are d = 25 mm and d = 20 mm, and both are made of steel (E = 210 GPa). Neglect the 214 3 m 3 m (1) P = 60 kN (2) 2 m B A C UA "Rigid" X P3.4-9
