A rigid horizontal bar ABC is supported by three vertical rods as shown. The system is stress free before the load is applied. After the load P is applied, the temperature of all three rods is raised by 110°F. Determine the magnitude of the normal stress in rod (2). Answer in MPa rounded-off to 2 decimal places. Rod (1) : E = 105 GPa; a= 22.0 x 10-6°C A=500 mm² Rod (2): E = 200 GPa; a = 11.7 x 10-6/°C A=250 mm² 2,100 mm 4,400 mm (1) (2) (2) P=45 KN 2,100 mm
