Transcribed Image Text:
An aluminium rod and a brass rod as shown in Figure 3 are connected to rigid walls at point A and C, respectively. At room temperature of 20°C, a 1.0 mm gap exists between the ends of the rods. For aluminium, the cross-sectional area, Aalu, modulus of elasticity, Ealu, and thermal expansion cooeficient, Calu, are 2500 mm², 70 GPa and 22.500 × 106/C, respectively, while for brass A, = 3500 mm², E = 105 GPa, and α = XX.XXX X106/°C. Take XX.XXX as your student ID. For example, if your student ID is MB19588, the XX.XXX = 19.588. (i) (ii) Determine the temperature at which will close the gap of 1.0 mm between the rods. Compute the normal stress in each rod if the temperature increases to 60°C.
