PROBLEM C. The given system below, consisting of a rigid horizontal bar ABC and supported by three vertical rods, is stress free before the load P is applied. For the rod at B: diameter, d=28 mm; length, L = 4400 mm; E= 200 GPa; for the rods at A and C: d = 24mm; length, L = 2100 mm; E = 100 GPa. Find the stresses develop in each bar when P = 55 kN and the system is subjected to a AT = 90c°. A B *p
