The figure as shown below is a rigid bar which is supported by two rods and a pin support. If the said connections is stress- free, determine the increase or decrease of the temperature in degrees Celsius that will resulted with a tensile stress of FN mPa for the brass rod. Brass L= 2 m A= 1200 mm? E= 100 GPa a = 18.7 x 10-/°C FN=70 MN=76 SN=50 B - 3 m- 2 m Copper L=3 m A = 1500 mm? E= 120 GPa a = 16.8 x 10-°C

Question
The figure as shown below is a rigid bar which is supported by two rods and a pin support. If the said connections is stress- free, determine the increase or decrease of the temperature in degrees Celsius that will resulted with a tensile stress of EN mPa for the brass rod. Brass L = 2 m A = 1200 mm² E = 100 GPa a = 18.7 x 10-/°C FN=70 B - 3 m - MN=76 2 m Copper L=3 m A = 1500 mm² E = 120 GPa a = 16.8 x 10-/°C SN=50 Note: Neglect the weight of the bar and assumes that the two rods will subjected to same temperature change
