Question 19
XE-DNAT2 marksNeeds review
At room temperature of 25°C, a gap of 1 mm exists between the ends of the rods 1 and 2 as shown. Given the cross section area A of the rods is 1500 mm², Young’s modulus E = 75 GPa and the coefficient of thermal expansion
. When the temperature has reached 150°C, the magnitude of normal stress in each of the rods (in MPa, rounded off to two decimal places) is
