Stainless steel has a young modulus' of 18*10^10 and a linear expansion of 17.3*10^-6. It is circular with a mean radius of 5.4 millimeter, a height of 4.0 millimeter and thickness of 0.46 millimeter. If a band fits snugly on the tooth when heated to 84.0 c. Determine what is the tension in the band when it cools to 37.0 c.
