- A poorly designed electronic device has two bolts attached to different parts of the device that almost touch each other in its interior as in the figure. The steel and brass bolts are at different electric potentials, and if they touch, a short circuit will develop, damaging the device. The initial gap between the ends of the bolts is d = 5.0 mm at 27°C. At what temperature will the bolts touch? Assume the distance between the walls of the device is not affected by the temperature change.
