Question
1) A copper collar is to fit tightly about a steel shaft whose diameter is 6.0088 cm at 18°C. The inside diameter of the copper collar at that temperature is 5.9800 cm. To what temperature must the copper collar be raised so that it will just slip on the steel shaft, assuming the temperature of both the steel shaft and copper collar are raised simultaneously? 1300 C Submit You currently have 3 submissions for this question.

1] At the required temperature, booth will have same diameter
d = dc*(1+ alphac delta T) = ds*(1+ alphas deltaT)
5.9800*[1+ 17e-6 deltaT] = 6.0088*[1+ 13e-6 deltaT]
1 + 17e-6* deltaT = 1.004816+13.0626e-6 deltaT
deltaT (17e-6 - 13.0626e-6) = 0.004816
deltaT = 0.004816/(17e-6 - 13.0626e-6)
= 1223
requied temperature = 1223+18
= 1241 degree C answer
