How does the thermal expansion of a material influence its structural design?
A l-m long steel bar (E = 200 GPa) of 10x10mm dimension fixed at one end and the other end having a gap of 0.5 mm from the fixed wall is heated by
90°C from initially 30ºC. What is the normal stress, in MPa, induced in the system due to change in temperature? Use a = 12 x 10-“ per °C. Encode you
answer in whole number.
Round your answer to 0 decimal places.
