Question

3) When measured at 20°C, a brass rod has outside diameter 2.002cm whilst a steel ring has outside diameter 2.800cm and internal diameter 2.000cm. The temperatures of the two objects is always the same. At what temperature will the rod just fit inside the ring? a) -125°C b) -105°C c) -45°C d) +125°C e) +145°C

Step 1

We need to find the temperature at which a brass rod will just fit inside a steel ring. We are given the dimensions of both objects at 20°C and the materials' expansion coefficients are implied to be known (since they are not provided in the question, we'll use Show more…
