Calculate the stress developed inside a tooth cavity filled with copper when hot tea at temperature of `57^(@)C` is drunk. You can take body (tooth) temperature to be `37^(@)Canda=1.7xx10^(-5)//""^(@)C`, bulk modulus for copper = `140xx10^(9)N//m^(2)`.
Text Solution
Verified by Experts
Stress = K `xx` strain = `K(DeltaV)/V=K(3alpha)Deltat` = `140xx10^(9)xx3xx1.7xx10^(-5)xx20` = `1.428xx10^(8)N//m^(2)` This is about `10^(3)` times atmospheric pressure.
