The band in the figure below is stainless steel (coefficient of linear expansion 17.3 x 10-6c-1, Young's modulus = 18 x 1010 N/m2). It is essentially circular with an initial mean radius of 5.4 mm, a height of 4.4 mm, and a thickness of
0.51 mm. If the band just fits snugly over the tooth when heated to a temperature of 81°C, what is the tension in the band when it cools to a temperature of 37°C?
