2. An 8 foot long aluminum I-Beam with a cross sectional area of 24 in² is placed between two walls when it is at a temperature of dry ice (-110°F). At this temperature the beam contacts both walls, but there is zero force between the beam and the walls. The beam and its surroundings are then heated to room temperature (75°F), (a) Determine the force the walls exert on the beam as a result of this temperature change. (b) Determine the axial stress in the beam as a result of this temperature change. (c) If the beam was not constrained by the walls, what would be its change in length? 국 8 ft
