Y.T.U Civil Eng. Dept. Mechanics Div. Spring 2021/22 Strength of Materials I Homework I Question 3 (30 p): At room temperature (20°C) a 0.5 mm gap exists between the ends of the rods shown. At a later time when temperature has reached 140°C, determine (a) the normal stress in the aluminum rod, (b) the change in length of the aluminum rod. 0.5 mm 300 mm 250 mm- Aluminum Stainless steel Modulus of Elasticity (GPa): E Cross-sectional area (mm²): 3xA Modulus of Elasticity (GPa): 2.5xE Cross-sectional area (mm²): A Thermal Expansion Coefficient (/°C): a=17.3x106 Thermal Expansion Coefficient (/°C): a=23x106 Parameters used in this question: E= Summation of the last three digits of the student number. For example, if student ID is 10212532 then E=5+3+2=10. If summation equals to zero, take E=10 A= Summation of the last two digits of the student number. For example, if student ID is 10212532 then A=3+2=5. If summation equals to zero, take A = 10 HONORA
