fulfilled. Problem 2: (9 Points) A bar with an initial length of lo = 1000 mm is placed between two solid plates as seen in the sketch below. The bar is then heated from room temperature (25°C) to a final temperature of 250° C. The thermal expansion coefficient of the material is a = 12.10-1/K] 25°C > 250°C a=12.10-6 [lk] Lo a) What is the thermal strain in % resulting from this rise in temperature ? b) What is the compressive stress in MPa acting against the plates ? c) What is the force in kN acting against the plates, if the bar has a cross section of A = 6000 mm?? f
