A piece of ceramic (= 4.5 x 10-6/C) with a fracture stress of 100 MPa and elastic modulus of 250 GPa is heated from 25C to 1025C in NOT allowing any expansion of the bar along its length. Will the bar fracture? SHOW WORK. (3 points) Do you expect KBr to have the CsCl crystal structure? Show work and explain. The ionic radii in pm are: K+ = 138, Br = 196.
