Question:
How does Metal Expansion effect things here on Earth like microwaves, ovens, car engines, guns,etc.?


Replies:
Do you mean because of heat?

Well if you do, these items are manufactured so that the expansion of the metal due to heating under normal operating temperatures will not distrub the function of the manufactured item. The classic example, is a bridge, which has joints that can expand when the temperatures are hot during the summer and contract during the cold winter months. Without these "tricks" the steel of the bridge would become stressed which leads to metal fatigue and failure.
