A hole is drilled in a steel plate. As the temperature of the plate increases, does the size of the hole increase, decrease or stay the same? Give a short and logical explanation why this occurs?
Homework Answers
As the temperature of the metal plate is increased , it's dimensions increase. Hence the hole becomes larger on size . To understand the effects related to thermal expansion on dimension you can imagine thermal expansion as magnification of the whole object . So if we magnify the plate , the hole will appear to be larger.
