- Question 1 A copper tube that experience a temperature change is placed between two rigid caps. Four steel bolts are symmetrically arranged parallel to the axis of the tube and are lightly fastened. The copper has a cross-sectional area, length, Young's modulus and coefficient of expansion of 2000 mm², 300 mm, 100 GPa and 16 x 10-6 /°C respectively. The steel has a diameter, Young's modulus and coefficient of expansi on of 22 mm, 200 GPa and 12 x 10-6/°C respectively. Find the stress in the tube if the temperature of the assembly is raised by 70°C 1.1 1.2 What load will each bolt carry at the raised temperature2. The 40mm diameter steel rod AB shown in Figure 2 is resting on frictionless rollers between two steel plates. End A is just touching the left hand steel plate. Steel plate Steel plate А 1500mm Imm Figure 2 There is a gap of 1mm between the end B and the right hand side steel plate. The temperature of the rod increases by an amount AT and this increase in temperature causes the two ends of the rod to press against the steel plates. This action causes the right hand steel plate to move to the right by 0.5mm while the left hand plate does not move. The Young's modulus value for steel is 210,00ON/mm?. Taking any assumptions that you deem necessary calculate the increase in temperature AT required to cause the rod to buckle.Question 1 A copper tube that experience a temperature change is placed between two rigid caps.
