Is this Duplo train track under too much tension?
My favorite part about this thread is not the first, very thorough, very mathematical and accurate answer, but the answer below it that has 0 upvotes but is by far the most practical:"I would first check for track flatness"This thread is a great example of how engineering is often NOT a solution to problems, classic "hammer and nail" territory here. And how engineers often ofterthink things unnecessarily ;)
