Q2. A thermo gate consist of an aluminum plate AB and a magnesium plate CD, each having a width of 15.X mm and fixed supported at their ends as shown in Figure Q2. If the gap between them is 1.5 mm when temperature is T,= 25.Y °C. (a) Determine the temperature, Trequired to just close the gap. X- The last digit of your matrix number Y– The fifth digit of your matrix number For example, a student with the matrix number CD150150 will have a width of 15.9 mm and T, = 25.7°C (8 marks) (b) Determine the axial force in each plate when the temperature T,becomes 100°C. (7 marks) Assume bending or buckling will not occur. Given E= 68.9 GPa, E= 44.7 GPa., as = 24(10)/°C,G = 26 (10-)/°C
