A 250mm long brass bar (CTE = 20.5X10-6/ 0C) is setup as shown below. Initially, when the temperature is 150C, there is a total clerance of 0.25mm between the right end (left end is secured to the left side support) of the bar and the right side support. At what temperature, the end of the bar will be in contact with the frame? When temperature of the bar rises to 900C, is there any stress developed in the bar? If yes, what is its magnitude?
