CalculaJe 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^(@) C and a = 1.7 xx 10^(-5)//^(0)C, bulk modulus for copper = 140 xx 10^(9) N//m^(2).

1.	CalculaJe 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^(@) C and a = 1.7 xx 10^(-5)//^(0)C, bulk modulus for copper = 140 xx 10^(9) N//m^(2).
Answer» SOLUTION :Stress K `xx ` strain = K `(Delta V)/(V ) = K (3 alpha ) Delta t ` ` = 140 xx 10^(9) xx 3 xx 1.7 xx 10^(-5) xx 20` `= 1.428 xx 10^(8) N//m^(2)` This is about `10^(3)` times atmospheric pressure.
