A3. The brass bar and the aluminum bar in the drawing are each attached to an immovable wall. At 28 °C the air gap between the rods isx=1.3 x 10 m. The coefficients for linear expansion for these metals are: AL2.3 x 10 C¹ and 19 x 10¹ °C). Brass Aluminum -2.0m- 1.0 m- a) Solve for the final temperature that will close the gap between the metals, set up ALA+ Alaxand solve for AT first. b) Confirm your results. Using that temperature calculate the linear expansion of the brass. e) Now calculate the linear expansion of aluminium. d) Do these add up to the gap distance x?
