Welcome to Ask an Engineer!
These are a series of questions submitted by visitors to our site and answered by members of MIT's engineering community—our faculty, graduate students, or postdocs. Their answers cover all disciplines in the practice of engineering (and sometimes wander well beyond them).
We have temporarily suspended our production of answers to new questions. We sincerely appreciate the many thoughtful and engaging questions we have received and plan to return to this project in the future. We are especially appreciative of the questions that have come from our younger visitors. Kids -- just because we're not answering questions on our site doesn't mean they're not out there. Keep looking!
