Presents the diagram of the problem, necessary formulas, clearance and numerical solution:
A poorly designed electronic device has two screws attached to different parts of the device that almost touch each other inside. steel bolts and brass are at different electrical potentials and if they touch, a short circuit will develop will damage the device. The initial separation between the ends of the screws is 5 μm to 27 ◦C. At what temperature will the screws touch? Assume that the distance between the walls of the device is not affected by temperature change and the coefficient coefficients of linear expansion αlaton = 19x10−6 ◦C −1 and αsteel = 11x10−6 ◦C −1
