Question

An iron tyre of diameter 50cm at 15°c is to be shunk into a wheel of diameter 50.35cm to be heated so that it will slip over the wheel with radial gap of 0.5mm
. Calculate the temperature to which the tyre should be heated.

The temperature to which the tyre should be heated can be calculated using the formula:

T = (50.35 - 50) / 0.5 x 15 + 15

T = 30.7°C
